By the numbers

Why people commit, and what they say makes it work.

Why people marry

90%of married U.S. adults said love was a major reason they got married (2019).
66%of married adults named companionship as a major reason (2019).
63%of married adults said wanting to make a formal commitment was a major reason (2019).

What makes it work

64%of married U.S. adults say shared interests are very important for a successful marriage (2016).
56%say sharing household chores is very important. Only 42% say the same about having enough income.
69%of conflicts between partners never fully go away, so how you handle differences matters.

Chemistry, compatibility and character

Why sparks are not enough on their own.

Chemistry, that rush of attraction, is real and it matters. But it tells you little about how someone will treat you when you are sick, broke, grieving or disagreeing. For the long term, character and shared values count for much more.

🔥 ChemistryAttraction and excitement. A good start, not a full picture.
Read more

Feeling drawn to someone is a normal and lovely part of falling in love. Affection that feels natural and mutual is one thing worth looking for.

Very intense early attention, gifts and “soulmate” talk within weeks can be love bombing, not chemistry. See “Green flags, red flags and taking it slow” below.
🧩 CompatibilityShared values, goals and ways of living.
Read more

Compatibility means your values and life visions line up well enough on the big things: family, career, money and what makes life meaningful.

You do not need the same hobbies or personality. Many happy couples are opposites in style but agree on what matters most.

💎 CharacterWho they are when things get hard.
Read more

Character shows in kindness, honesty, follow-through and how someone handles stress and conflict. These traits shape daily life together far more than looks or status.

Watch for

  • How they act when they are tired or stressed
  • How they speak about people who are not in the room
  • How they treat people who can do nothing for them
  • Whether they keep small promises
Time helps. Seeing someone across seasons, stresses and big moments shows you much more than the first exciting months.

Traits that matter most for the long run

Kindness, emotional skills, trust and more.

Drawing on decades of couples research, the Gottman Institute lists qualities worth looking for in a long-term partner. Tap each card to learn what they look like in real life.

💗 Kindness and compassionEveryday care, especially when you are struggling.
Read more

A kind partner shows everyday consideration and offers comfort when you are down. Small daily kindnesses are linked with happier, steadier marriages.

Signs

  • Checks on you when you are sick or stressed
  • Is gentle when you make a mistake
  • Notices what you need without being asked every time
🧠 Emotional intelligenceManages their own feelings and notices yours.
Read more

Emotionally intelligent partners manage their own emotions, pick up on yours, and take your feelings seriously instead of brushing them off.

🔒 Trustworthiness and loyaltyTells the truth, follows through and chooses you.
Read more

A trustworthy partner keeps their word, is honest and consistently chooses the relationship. In healthy relationships, partners can believe each other without needing proof all the time.

🫂 Emotional availabilityLets you in, and lets you support them.
Read more

An emotionally available partner shares their inner world, their worries and dreams, and lets you care for them too, instead of avoiding closeness.

🌱 Willingness to growOpen to feedback and change.
Read more

People with a growth mindset see problems as chances to learn. They can hear “That hurt me” without falling apart or attacking, and they try to do better.

😄 Humor and hopeCan find lightness on hard days.
Read more

A sense of humor and a hopeful outlook help couples get through stress, as long as it does not mean pretending everything is fine.

📣 Supportive and encouragingChampions your goals, and is honest too.
Read more

A supportive partner cheers you on and wants you to grow, while still being honest when they have concerns.

Nobody has every trait all the time. Look for the overall pattern, and for someone who is willing to work on the gaps, just as you are.

Shared values and life vision

The big conversations to have before you commit.

Shared core values and a similar picture of the future are among the most important things to look for in a long-term partner. Talk about the big topics early, kindly and more than once. Views can change over time.

👶 ChildrenWhether, when, how many, and how to raise them.
Read more

Wanting or not wanting children is one of the hardest differences to compromise on. In healthy relationships, partners can talk openly about their choices and parent in ways they both feel okay with.

Questions to ask

  • Do you want children? Why or why not?
  • How do you picture discipline and family life?
  • What if we can’t have children?
  • Would you consider adoption or fostering?
🕊️ Faith and meaningBeliefs, traditions and what makes life meaningful.
Read more

Couples do not need the same beliefs to thrive, but they do need respect for each other’s beliefs and a plan for things like holidays and raising children.

Questions to ask

  • What role does faith or spirituality play in your life?
  • Which traditions matter most to you?
  • How would we handle our differences with family and children?
🏙️ Where and how you liveLocation, careers and lifestyle.
Read more

Big choices like where to live, whose career comes first in a move, and how much you travel or socialize shape daily life together.

Questions to ask

  • Where do you see us living in 5 or 10 years?
  • What would happen if one of us got a job far away?
  • What does a good weekend look like to you?
🍷 Health and habitsAlcohol, drugs, gambling, health and self-care.
Read more

Habits around alcohol, drugs, gambling, sleep and health affect a household. It is okay to ask about them, and to share your own honestly.

If a partner’s drinking, drug use or gambling worries you, the app has guides on substance use and gambling, including how to support someone.
Use the “Big conversations checklist” worksheet to plan these talks.

How they handle conflict and stress

Your first disagreements tell you a lot.

Every couple disagrees, and about 69% of conflicts never fully go away. So the question is not whether you will argue, but how. Watch how a partner acts during your first real disagreements.

🟢 Healthy signsCalm, fair and willing to repair.
Read more

A partner with good conflict skills stays fairly calm, takes breaks when needed, and apologizes and forgives sincerely. They state needs without attacking and listen to understand.

It looks like

  • “I need a break, can we talk in 30 minutes?”
  • “I see why that upset you. I’m sorry.”
  • “What would help us not end up here again?”
🐎 The Four HorsemenCriticism, contempt, defensiveness and stonewalling.
Read more

Gottman research names four patterns that predict trouble: attacking character (criticism), mocking or disgust (contempt), blaming back (defensiveness) and shutting down (stonewalling). Contempt is the single biggest predictor of divorce.

Everyone slips into these sometimes. What matters is whether they are a constant pattern, and whether the person can notice and change.

🌪️ Under pressureHow they act when life gets hard.
Read more

Notice how someone handles a missed flight, a job setback or a family crisis. Do they turn toward you, or lash out? Do they take responsibility, or blame everyone else?

Fear is never a conflict style. If a partner threatens you, breaks things, blocks you from leaving or makes you afraid to disagree, that is a sign of abuse. You can talk to an advocate at love is respect or the National Domestic Violence Hotline (see “When and where to get help”).

Respect, equality and room to be yourself

Healthy partners share decisions and support your independence.

The National Domestic Violence Hotline describes healthy relationships as built on respect, trust, honesty, open communication, equality and healthy boundaries. These are worth looking for from the very start.

🙇 RespectYour opinions, feelings and needs matter.
Read more

A respectful partner values your opinions, feelings and needs, and supports you in being yourself.

🤲 EqualityBig decisions are made together.
Read more

In a healthy relationship, major decisions are made together and both partners have fair access to money and other resources.

Partners who accept each other’s influence, letting the other’s view shape decisions, tend to have happier, longer-lasting marriages.

🌻 Room to be yourselfYour own friends, interests and time apart.
Read more

A good partner keeps their own identity and relationships and respects yours. Wanting time apart is normal, not a threat.

Jealousy that tries to control who you see is not proof of love. See Green flags & red flags in relationships.
🛑 Respecting “no”Including about touch, sex and pace.
Read more

In healthy relationships, partners only do sexual things both people freely agree to, and can talk openly about comfort levels. Someone who pressures you or sulks when you say no is showing you how they handle your limits.

Family, culture and the people around you

You often build a life with their world, too.

A long-term partner usually comes with family, friends, culture and history. You do not need to love everyone in their life, but it helps to understand how those relationships work and how your partner handles them.

👨‍👩‍👧 What they learned growing upFamilies pass down ideas about love, money and fighting.
Read more

Early relationships with caregivers shape how people connect, trust and handle closeness as adults. These patterns can change with awareness and effort.

Questions to ask

  • How did your parents handle arguments?
  • How was love shown in your home?
  • What do you want to do the same, or differently?
🧓 Boundaries with familyWill they stand with you as a team?
Read more

Notice whether your partner can kindly set limits with their own family when needed, and whether they speak up for you. Being a team often means putting the partnership first.

If family or culture is causing pressure, see When family or in-laws don’t accept your relationship.
💔 How they talk about exesPatterns can repeat.
Read more

Someone who calls every ex “crazy” and takes no responsibility for any breakup may struggle to own their part in future problems. Someone who can reflect honestly on what went wrong is a good sign.

👯 What your people thinkTrusted friends can see what you miss.
Read more

Friends and family who care about you may notice things you can’t see when you are in love. Their concerns are worth hearing, even if the decision is yours.

Money, chores and everyday life

The daily details that make or break a shared home.

Married Americans put sharing chores ahead of having enough income when asked what makes a marriage successful: 56% vs 42%. Everyday fairness matters a lot.

💸 Money stylesSaver, spender, worrier, avoider.
Read more

People bring very different money habits and fears into a relationship. Talking openly about income, debt and goals before combining lives can prevent painful surprises later.

Questions to ask

  • Do you have debts I should know about?
  • Are you more of a saver or a spender?
  • Joint accounts, separate accounts, or both?
  • What does money mean to you?
Money in families & relationships has a “Money talk for two” worksheet. This is general information, not financial advice.
🧽 Sharing the homeWho does what, and does it feel fair?
Read more

Notice whether a partner pitches in without being asked, notices what needs doing, and is open to talking about fairness.

The mental load guide explains the invisible planning work that often falls to one person.
⏰ Daily rhythmsSleep, social life and alone time.
Read more

Early bird or night owl, homebody or social butterfly: these differences are workable when you talk about them and plan for both people’s needs.

Green flags, red flags and taking it slow

Trust your gut, and let a relationship unfold over time.

Green flags are signs of safety and respect. Red flags are signs of control, disrespect or danger. The Green flags & red flags in relationships guide covers these in depth. Here is what matters most when thinking long term.

💣 Love bombingToo much, too fast.
Read more

Love bombing is when a new partner showers you with intense attention, affection and gifts early on, often pushing past your pace. It can be a red flag for an unhealthy or abusive relationship.

Signs

  • Constant calls or texts that feel overwhelming
  • Costly gifts that come with strings
  • Over-the-top compliments from someone you just met
  • Pressure to drop friends or spend all your time together
  • Saying “I love you” or “soulmate” within weeks
🐢 Going at a pace you both chooseHealthy love can wait for you to be ready.
Read more

Someone who pressures you to move in, marry or have children before you are ready is not respecting your pace. A good partner wants you to say yes freely.

🫀 Trust your gutHow do you feel around them?
Read more

If something feels off, take that seriously. Talk with your partner about behavior that makes you uncomfortable, and lean on trusted friends if you are unsure.

Good signs

  • You feel calm and like yourself
  • You can disagree without fear
  • You can say no and it is respected
  • You feel more connected to friends and family, not less
A wedding, a move or a baby will not fix serious red flags. Problems like control, cruelty or abuse usually grow over time, not shrink.

Knowing yourself first

Your patterns, needs and deal-breakers.

Choosing well is also about knowing what you need, what you can offer, and what patterns you tend to repeat. This is not about being “fixed” first. It is about choosing with open eyes.

🔗 Your attachment patternsHow you tend to act when you feel close or unsure.
Read more

Attachment styles describe how people tend to connect, trust and react when they feel close or worried about losing someone. They come from early relationships and can change over time.

The Attachment, love & intimacy guide explains each style and how to move toward security.
✅ Must-haves vs nice-to-havesSeparate what you need from what you’d like.
Read more

Must-haves are things you truly can’t live without, like kindness, honesty or agreeing on children. Nice-to-haves, like a shared hobby or height, matter far less over time.

Use the “My must-haves, nice-to-haves & deal-breakers” worksheet.
🔁 Patterns from the pastNoticing if you keep choosing the same kind of hurt.
Read more

If past relationships have followed a painful pattern, like choosing partners who are unavailable or controlling, it can help to talk it through with a therapist before committing again.

🙌 What you bringThe qualities you hope for, you can offer too.
Read more

Kindness, honesty, conflict skills and willingness to grow are things you can build in yourself as well as look for in someone else.
