Spark is real. It is not a plan.
You meet someone and your stomach flips. Three weeks later you are making plans in your head, and you have barely noticed how they spoke to the waiter or whether they called when they said they would.
That rush feels like an answer, but it is a feeling. Researchers from 29 labs pooled 43 long-term studies of couples [1]. The strongest predictors of a good relationship were how it felt to live in it: believing your partner is committed, feeling appreciated, a good sex life, believing your partner is happy, and low conflict [1]. Those relationship experiences explained up to 45% of the differences in how happy people were with their relationship at the start of the studies [1]. You can only learn those things over time, by watching how someone behaves. This Expert guide shows you how to do that on purpose, with exact steps, what to do when a step does not work, and how to tell whether you are getting better at it.
Those relationship experiences explained up to 45% of the differences in how happy people were with their relationship at the start of the studies [[1]].
How choosing a partner works
Two systems run at once when you date. The first is fast: attraction, nerves, the pull to see someone again. The second is slow: you learn, date by date, whether this person is kind, reliable and steady. The fast system is loud early. The slow system is what you will live with.
Large studies of married couples show why the slow system matters. In nationally representative samples of 5,278 couples in Australia, 6,554 in the United Kingdom and 11,418 in Germany, a partner's personality shaped the other person's relationship happiness, and the partner traits that mattered most were agreeableness, conscientiousness and emotional stability [2]. In plain words: kind, reliable and calm under stress. How similar the two partners were explained less than half of one percent of their satisfaction once each person's own personality and their partner's were taken into account [2]. So "we are so alike" matters far less than "they are kind to me when things go wrong."
The fast system is not useless. In a Dutch study of 137 married or living-together couples, partners who fell in love at first sight got together faster, and did not report lower relationship quality than couples who got together slowly [3]. Spark is fine. The trouble starts when spark stops you from checking substance. The five steps below make sure you check.
Step 1: Write What You Want and What You Won't Accept
WHY THIS MATTERS
What you write down before you meet someone does shape who you end up with. In the Göttingen Mate Choice Study in Germany, researchers asked 763 single people aged 18 to 40 what they wanted in a partner, then followed them for 5 months [4]. The preferences they stated beforehand predicted the traits of the partners they later found [4].
There is a catch. When a new partner fell short of what people had said they wanted, they adjusted their preferences down to fit; when a partner was better than hoped, there was no matching shift [4]. Liking someone bends the list. A written list, made before you meet, is your record of what you wanted when you were thinking clearly.
The "no" column matters most. Across 6 studies with more than 6,500 people, people weighed deal-breakers more heavily than they weighed deal-makers, and deal-breakers counted for more in long-term relationships than short-term ones [5]. People in committed relationships showed this pattern more strongly too [5]. One clear "no" protects you more than ten nice extras.
Finally, you cannot have everything, so rank. In a study of 2,477 people from Eastern and Western countries, participants designed an ideal long-term partner by spending a small or large budget of "mate dollars" across 8 traits [6]. With a small budget, people from both regions spent first on a few core traits, even though culture changed how they spent on almost every trait [6]. A small budget shows you what you treat as a necessity.
- Take 10 minutes and write three columns: must-haves (up to 5), nice-to-haves (as many as you like), and deal-breakers (3 to 5).
- Write must-haves as things you can see someone do: "keeps promises", "stays kind when angry", "says sorry and means it", "is interested in my day". Put height, job title, income bracket and looks under nice-to-haves unless one of them truly is a must for you.
- Run the budget test. Give yourself 20 points to spread across your must-haves and nice-to-haves. Then cut it to 10 points. Whatever still gets points at 10 is a true necessity [6]. Move anything that gets zero at 10 points down to nice-to-have.
- Add one line each on six life topics: children (yes, no, open, how many), faith (shared, respected, not important), money (saver, spender, joint or separate), where to live (city, country, near family), sex and affection (how often, how shown), and how you like to spend an ordinary week. For each, write what you want and where you could bend.
- Write your deal-breakers as behaviour, not labels. "Shouts at me", "lies about money", "doesn't want children when I do", "keeps me from my friends".
- Date the page and keep it somewhere you will see it, such as your phone notes.
- Read the list before each first date and again after the third date with anyone you like.
When it isn't working
- Your list keeps growing. Long lists usually mean the nice-to-haves have crept into the must-have column. Redo the 10-point budget test [6] and keep only what still gets points.
- You keep making exceptions for one person. That is the downward shift the Göttingen study found [4]. Ask: "If a stranger had this trait, would I still accept it?" If not, it is still a deal-breaker.
- You don't know what you want. Look at what made past relationships feel good on an ordinary day, and what made you feel small. Write those as behaviours. Step 2 helps with this.
- Everything feels negotiable. Pick the one thing you would leave over. That is your first deal-breaker. Then find two more.
For different situations
- If you have children, add a must-have about how they treat children and how they would fit into your family's routine.
- If faith or culture shapes your life, write how much it must be shared and how much it must be respected. These are different lines.
- If you are not sure you want a life partner right now, write that at the top of the page. Readiness itself has its own article in Go further.
Within a week you can say in one line whether a person fits your must-haves, and you notice a deal-breaker instead of explaining it away.
Step 2: Ask Two Friends What They See in Who You Pick
WHY THIS MATTERS
You see your own dating life from the inside. Friends see it from the outside. In a 3-wave study of dating couples in North America, the couple's friends judged the relationship more negatively than the couple did [7]. Both the couple's views and their friends' views predicted whether the couple stayed together, and the woman's friends were especially good at predicting break-ups [7]. Friends knew more when the couple had told them about the relationship [7]. So a friend's view is only as good as what you share with them.
This step uses that outside view twice: once to name what you tend to pick, and again, with each new person, as an early check on what you might be missing.
- Before you talk to anyone, jot a quick 3-line map of your last 2 or 3 relationships: how each started (fast or slow), what went wrong, how it ended. This gives your friends something concrete to react to.
- Pick 2 friends who knew you during at least one of those relationships and who will be honest with you.
- Ask each one, separately: "What do you notice about the people I pick?" and "When did you first have doubts about my last partner?" Write down their words, not your reply.
- Don't argue. Thank them. You can disagree later, on paper.
- Put what they said next to your map, and write what you pick in one sentence. For example: "I fall for people who are exciting at first and unreliable later."
- Turn that sentence into one early warning sign you can spot on a first or second date, and add it to your list from Step 1.
- With someone new, tell your 2 friends the real details as things go along: what they did, how you felt, what worried you. Friends predict better when they hear more [7].
- After the third date with anyone, ask one friend: "From what I've told you, what stands out?"
When it isn't working
- Your friends say "they all seemed nice." Ask a sharper question: "What did they do that you would not accept from a partner?" or "When did I seem least like myself?"
- You only tell friends the good parts. That leaves them guessing. Share one worry along with each good thing.
- Your friends dislike everyone you date. Ask what exactly they saw. A specific behaviour ("they mocked you in front of us") counts. A vague dislike counts less.
- Your friends are part of the problem. If friends push you toward people who treat you badly, ask a different trusted person, such as a sibling, mentor or counsellor.
- Looking back brings up pain. Keep this step to the friends' view. Working through why a pattern happens, and forgiving yourself for it, is a separate article in Go further.
Within 2 weeks you can say in one sentence what your friends see in who you pick, and you have 2 people who hear the real details about anyone new.
Step 3: Score Spark and Substance Separately After Every Date
WHY THIS MATTERS
After a date, one big feeling tends to swallow everything else. Splitting it into two scores stops that. Spark is how strongly you are drawn to them. Substance is how they behave: kind, honest, steady, interested in you.
Substance is what the evidence says to weight. In the three national couple samples, the partner traits that most shaped the other person's satisfaction were agreeableness, conscientiousness and emotional stability [2]. In the pooled 43-study analysis, the things that predicted a good relationship were relationship experiences such as appreciation, commitment and low conflict, not individual traits on their own [1]. Your own experience of being with them counted two to four times more than the partner's ratings [1]. So how you feel around them, over many ordinary days, is real data.
Spark is still allowed. Couples who fell in love at first sight did as well as couples who started slowly [3]. The aim is not to avoid spark. It is to stop spark from hiding low substance.
- Within a few hours of each date or long call, open your scorecard (a note on your phone works).
- Rate spark from 0 to 10: how much you want to see them again, how drawn you feel.
- Rate substance from 0 to 10 using 5 quick checks, each worth 0, 1 or 2 points: Were they kind (to you and to others)? Were they honest and consistent with what they had said before? Were they steady, or did their mood swing? Were they interested in you, with questions and follow-up? Did you feel calm and like yourself?
- Add 3 short lines: one green flag, one red flag, and "How did I feel around them: calm, anxious or drained?"
- Use the scores to decide what happens next:
- High substance (7 or more), any spark: go on another date. Low spark with high substance deserves 2 or 3 dates before you decide.
- High spark, low substance (4 or less): slow down. Do not skip ahead to exclusivity or big plans.
- Low spark, low substance: thank them and move on.
- Never let spark raise the substance score. If you catch yourself writing "but they were so funny" next to a red flag, the red flag stays.
- After every 3 dates with the same person, look at the substance scores side by side. Rising or steady is good. Falling is information.
When it isn't working
- Every score is 9 or 10. You are probably scoring hope. Score the behaviour you saw, not what you expect. Ask: "What exactly did they do that earned this point?"
- Every score is low. Check your list from Step 1. If most people fail, a nice-to-have may be sitting in the must-have column. The article on calibrating your standards, in Go further, goes deeper.
- You feel anxious and call it spark. Some people feel a strong pull toward someone who is unpredictable. If you often wrote "anxious" in the feeling line, lower the weight you give spark for now.
- You forget to score. Set a phone reminder for the evening of each date.
Reading your scores over time
Your scorecard is a record, not a verdict. What matters is the pattern over 3 to 6 dates: whether substance stays high when they are tired, stressed or disappointed. A person who is kind only when things go their way will show a drop in substance the first time a plan goes wrong.
Within a month you decide on how someone treats you instead of on the rush, and you can show yourself, in writing, why you are seeing someone again.
Step 4: Screen Early: Meet Soon, Keep It Short, Watch How They Treat Others
WHY THIS MATTERS
You learn more from one hour face to face than from weeks of messages. A short, early meeting tests the real person before a story about them forms in your head.
How someone treats other people is a preview of how they will treat you once the effort of early dating fades. Watch for control from the start: the World Health Organization counts controlling behaviours as a form of intimate partner violence [8], and about 1 in 3 women worldwide have been subjected to violence by a partner or sexual violence by someone else in their lifetime [8]. Early on, it can look small: jealousy, checking your phone, or telling you who to see [9]. A full check of whether any relationship is healthy is its own article in Go further; here you use a short first date to catch the first signs.
- After 3 to 5 good messages, suggest meeting within 1 to 2 weeks. If they keep putting it off past 3 weeks, move on.
- Keep first dates to 60 to 90 minutes: coffee, a walk or a casual lunch, in a public place, with your own way there and home. The full safety plan, including video calls and photo checks before you meet someone from online, is in the safety article in Go further.
- Watch how they treat servers, drivers and strangers. Are they polite when the coffee is wrong? Do they thank people?
- Listen to how they talk about family and their ex. Some sadness or frustration is normal. "All my exes were crazy", said with no sense of their own part, is a red flag.
- Watch for contempt: eye-rolling, mocking, sneering, or jokes at your expense. Count it as low substance, however strong the spark.
- No second date after a serious red flag: jealousy, asking to check your phone, pushing past a "no", telling you who you can see, or anger at small things [9] [8].
- Fill in your spark and substance scores (Step 3) the same evening.
When it isn't working
- You can't get to a meeting. If they refuse to meet or video call for weeks, treat that as an answer.
- First dates feel like interviews. Do something side by side, like a walk or a market. You will see how they treat others without asking a single question.
- They are lovely on dates but vague about their life. Ask to meet once in a setting that is part of their real week, such as a walk near where they live or a coffee with one of their friends.
- You explained a red flag away. That is normal. Go back to your list: if a stranger did this, would you accept it?
- They were rude to a server but lovely to you. The kindness you saw toward the server is the better preview. Score it under substance.
For different situations
- If you have been hurt before, keep first dates under an hour and use your deal-breaker list without exceptions.
- If you are dating after a long break, a script helps: "I'd love to meet for coffee this week. Does Thursday at 5 suit you?"
- If you are shy or anxious, plan a set end time before you go ("I've got a thing at 7"), so the date has a clear shape.
Within a month, good chats turn into real meetings within 2 weeks, and you have a record of how each person treats other people as well as you.
Step 5: Talk Through the Big Topics Within 3 Months and Track Kept Promises
WHY THIS MATTERS
Spark settles into everyday life, and plans and kept promises are what remain. Canadian psychologists described trust in close relationships as three layers that build in order: predictability (they do what they say), dependability (you can rely on who they are), and faith (confidence in a shared future) [10]. In their study, love and happiness were closely tied to that last layer, faith [10]. You build the first layer by noticing, week by week, whether words match actions.
The big life topics are where your list from Step 1 meets real life. In a Finnish study of 624 people in couples expecting a child, both partners were more satisfied when they were similar in how much they valued making their own choices, while being alike in personality made no difference [11]. So check values and life plans, not whether they are a copy of you.
The pooled 43-study analysis found that whether a relationship got better or worse over time was very hard to predict from questionnaires [1]. That is why you watch behaviour over weeks rather than trusting one great conversation.
- With someone serious, talk through 6 topics within about 3 months: children, faith, money, where to live, careers, and family duties (caring for parents, holidays, how involved families will be). Add sex and affection when the relationship is ready for it.
- One topic per date is enough. Bring it up lightly: "Can I ask a big one? How do you picture a normal weekend in 5 years?"
- Ask open questions and listen for specifics: "How did your family handle money?" "What does faith look like in your week?" "Where do you see yourself living?" "Whatever you want" is not an answer yet; ask again later.
- After each talk, mark the topic in your notes: agree, can bend, or deal-breaker. One real deal-breaker is enough to stop, even if everything else fits [5].
- Each Sunday, write one line: Did plans happen? Did they call when they said? Did their words match what they did? Mark the week kept, mostly kept, or not kept.
- If promises keep slipping, say it once, kindly and clearly: "When you say you'll call and don't, I feel unimportant. Can we fix that?" Then watch for 2 to 3 weeks to see if it changes.
- At about 3 months, review: your 6 topics, your weekly lines, and your substance scores from Step 3. Decide on purpose whether to go deeper, slow down, or end it.
When it isn't working
- They avoid every big topic. Name it gently: "I notice we skip the future stuff. Is that a hard area for you?" If they still avoid it after 3 months, that is information. Raising a timeline with someone who won't commit is its own article in Go further.
- You agree on everything. Check you are hearing their view and not your own. Ask for an example from their life: "When did you last…?"
- You disagree on one topic and can't tell if it's a deal-breaker. Ask yourself if you could live with their answer for 10 years without resentment. If not, it is a deal-breaker.
- Promises slip only when they are stressed. Note it, but watch how they repair it. Saying sorry and changing what they do builds dependability [10].
- You raised it once and nothing changed. You have your answer about this pattern. Decide whether it is a nice-to-have or a must-have, using your list.
Before you commit, you know where you agree, where you can bend, and whether this person keeps their word.
Special groups
- Single parents: keep your children out of the early dates and use Step 5 to test fit with your family before introductions. Add your children's needs to your must-haves.
- People who have lived through abuse: follow Step 4 without exceptions, and ask a counsellor or helpline to help you build your red-flag list. Controlling behaviour is a form of partner violence [8], and it often starts small [9].
- People from close-knit families or faith communities: the six big topics may involve your family. Write which decisions are yours and which you want to share, and keep your deal-breakers even when there is pressure.
- Older adults and people dating again after loss or divorce: your list may change a lot from your last relationship. Write it fresh rather than copying your old one.
- Same-sex and queer daters: the steps apply the same way. Choose friends for Step 2 who understand your dating world.
Myths
- "You'll just know." The instant feeling is not a reliable signal either way. Couples who fell in love at first sight did not do better or worse than slower couples [3]. What predicts a good relationship is how it feels to live in it over time [1].
- "Opposites attract, or you need someone just like you." Neither. Couple similarity explained less than half of one percent of satisfaction in very large samples [2]. The partner's kindness, reliability and steadiness mattered more [2].
- "Lists don't matter, love finds a way." Preferences written before dating predicted the traits of the partners people later found [4].
- "Your friends are just jealous." Friends' views predicted break-ups, and the woman's friends were especially accurate [7].
- "Jealousy shows they care." Accusing you of flirting or affairs and checking your phone are on the NHS list of signs of emotional abuse [9].
FAQ
How many dates before I know? There is no set number, but low-spark, high-substance people deserve 2 or 3 dates, and the big topics take about 3 months. Over time, how it feels to be in the relationship is the best guide [1].
What if I have no deal-breakers? Most people do once they think about it. In the deal-breaker studies, people weighed what they avoid more than what they want [5]. Start with one thing you would leave over.
Is it cold to score someone? The scorecard is private, and it protects both of you from a decision made on one rushed feeling. It also helps you notice good qualities you might miss when spark is low.
My list changed after I met someone. Is that bad? Lists can grow as you learn. But people tend to lower their preferences to fit a partner who falls short [4]. If a change only ever moves down, and only for one person, check it with a friend.
Do men and women want different things? Culture changes how people prioritise, but in a study across Eastern and Western countries, both regions spent a small budget first on a few core traits [6]. Your own written list matters more than averages.
What if they show contempt only once? One eye-roll on a bad day is not a pattern. Being put down or mocked again and again is a warning sign [9]. Note it in your scorecard and watch.

When to get help
Talk to a counsellor or therapist if you keep choosing partners who hurt you, if dating brings up panic or very low mood, or if you find it hard to leave someone who treats you badly. If you feel afraid of a partner, or you have changed what you do because you are afraid of what they might do, those are signs of an abusive relationship [9]. Find a free helpline at findahelpline.com, or call your local emergency number if you are in danger.
Track it
For the next 7 days, track one thing: fill in your scorecard after every date or call with someone you are dating (spark 0 to 10, substance 0 to 10, one green flag, one red flag, how you felt). Check again on day 21 and day 90. By day 21, every date should have a score, and you should not have gone on a second date with anyone who showed a serious red flag. By day 90, anyone serious should have 6 big topics marked and 12 Sunday lines on kept promises.
