Ask ten people what makes a relationship successful and you will get ten answers, because success means different things. For some it is longevity. For others it is feeling understood, raising a family together or simply being content.
This guide begins by defining success on your own terms, then walks through seven keys that West Virginia University’s health team, the Harvard Study of Adult Development and Gottman’s research all point toward. It also gives a simple weekly check-in method you can try. It is general information, not professional advice.
Key Takeaways
- A successful relationship is one where both people feel respected, safe and able to be themselves, not one without conflict.
- WVU lists honest communication, mutual respect and trust, shared values and goals, teamwork, consent, and quality time together and apart as foundations.
- The Harvard Study of Adult Development concluded that good relationships keep us happier and healthier.
- Repair attempts during arguments predicted happiness and stability among 130 newlyweds followed for six years.
- Success does not mean staying in an abusive relationship, and the National Domestic Violence Hotline is 1-800-799-7233.
First, Define What Success Means to You
What makes a relationship successful depends partly on what the two of you want. Before you look at research, ask each other three questions: What does a good relationship look like to you in five years?
What would make you feel supported? What would you consider a deal breaker? Your answers may differ, and that is useful information.
The sources reviewed use health and stability as their measures. The Harvard study measured happiness, health and longevity, while the Love Lab study measured happiness and stability.
Neither measures romance, passion or achievement, so when you ask what makes a relationship successful, these studies answer in terms of wellbeing, so a successful relationship in these studies means a relationship that is good for the people in it.
Why Success Is Not the Same as Staying Together
Staying together is easy to measure, so it is often used as a stand-in for success. But a couple can stay together for years while one or both feel lonely, afraid or controlled. When people ask what makes a relationship successful, the better question is if each person is doing well inside it.
The WVU description of a healthy relationship, with its emphasis on respect, safety and being able to be yourself, is a more useful yardstick than length. Treat the seven keys below as ways to check how both of you are doing, not as a pass or fail test.
Key 1: Honest Communication
West Virginia University’s guide to a healthy relationship puts honest communication first among its foundations, and lists little or no communication among the warning signs. Honest does not mean blunt.
Gottman’s work, as summarized by a therapist at Symmetry Counseling in an article on the four horsemen, recommends a gentle start-up with “I” statements in place of criticism. This is among the keys to a successful relationship that most couples can practice at once.
Key 2: Mutual Respect and Trust
Respect and trust appear together on the WVU list. In Gottman’s framework, contempt, which involves blaming, disrespecting and taking a superior position, is a pattern that can predict the end of a relationship.
The antidote is a culture of appreciation: remembering your partner’s positive qualities and naming them. Trust grows when words and actions match, over time.
Key 3: Shared Values and Goals
WVU lists shared values and goals as a foundation. You need not agree on everything, but the big questions deserve early honest talk: where to live, whether to have children, how to treat family, how to handle time and money.
The sources reviewed do not say which topics matter most, so use your own list. Partners who share direction can disagree about the route and still feel like a team.
Key 4: Teamwork
Teamwork means facing problems together. When you describe an issue as “us versus the problem,” both people are on the same side. Gottman’s antidote for defensiveness, acknowledging your part in the problem, supports this, because it shows you value solving the issue more than winning.
Teamwork is one of the successful relationship tips that shows up in daily life, and it is easy to practice when you ask yourself what makes a relationship successful in the small moments, in chores, plans and how you support each other through stress.
Key 5: Repair After Conflict
Psychology Today’s piece on turning a fight into a connection describes the Love Lab study in which researchers observed 130 newlywed couples and followed them for six years. Regular, effective repair attempts during intense arguments predicted both happiness and stability.
Couples who later divorced either made no repair attempts or their partners did not accept them as sincere. If you want a short answer to what makes a relationship successful, repair is a strong candidate.
Key 6: Consent and Safety
WVU lists consent in intimacy as a foundation and feeling pressured as a warning sign. More broadly, a relationship cannot be successful if one person is unsafe. WVU lists hurtful or threatening communication, mistreatment including verbal, physical or sexual violence, controlling or manipulative behavior and isolating you from other people among the signs of abuse.
Success includes feeling safe. If you are wondering what makes a relationship successful, start by asking if you feel safe and respected, because every other key depends on that.
Key 7: Time Together, Time Apart, and a Wider Circle
WVU lists quality time together and apart as a foundation. The Harvard Gazette’s report on the Harvard Study of Adult Development says the study began in 1938 with 724 participants and has grown to about 2,500, and found that people with more social connections to family, friends and community were happier, physically healthier and lived longer.
A couple that keeps friends, family and interests alive gives the relationship more to draw on. This is part of what makes a relationship successful when stress arrives, since no single partner can meet every need.
How to Have a Successful Relationship: A Weekly Check-In
Keys are only useful when practiced. The following check-in is a suggested method based on the research above, not a clinical program. Choose a calm time each week, put phones away, and keep it to about twenty minutes.
- Appreciation round: Each person names two specific things they valued this week.
- Logistics: Cover the calendar, money and chores quickly so they do not leak into other conversations.
- One concern each: Raise it with a gentle start-up, such as “I felt left out when plans changed.”
- One request each: Ask for something small and specific.
- Close warmly: End with a hug, a plan for the weekend or a shared laugh.
Couples who do this often find that small problems get handled before they grow, which is a practical way of answering how to have a successful relationship in a busy week. It also puts the 5:1 ratio of positive to negative interactions in practice, because the check-in itself starts and ends with positives.
What Makes a Relationship Successful Over Time
Relationships change as people do, so what makes a relationship successful in your twenties may need adjusting in your forties. A new job, a move, a child, an illness or caring for a parent all change the balance.
The keys stay the same, but the ways you practice them shift. Revisit your goals once or twice a year, and treat changes as normal.
Keys to a Lasting Relationship Versus a Happy One
Lasting and happy are not always the same thing. A relationship can last for decades without being good for either person, and a shorter relationship can be healthy and valuable.
The sources reviewed measure happiness and stability, not length for its own sake. If you are seeking the keys to a lasting relationship, check that the foundations above are also present, so that staying together means being well together.

What the Research Cannot Tell You
The Love Lab study followed newlywed couples and the Harvard study followed a specific group and their families, so neither speaks for every culture, age or relationship type. The sources reviewed do not rank the keys or put numbers on how much each contributes.
They also do not guarantee that any approach will work. Use the keys as questions to discuss together, not as a scorecard.
FAQs
What makes a relationship successful in the long run?
The sources reviewed point to honest communication, respect and trust, shared goals, teamwork, repair after conflict, consent and wider social connection.
Do successful couples fight?
Yes. The Love Lab study found repair attempts predicted happiness and stability, not the absence of arguments.
Is a long relationship the same as a successful one?
No. The sources measure happiness, health and stability. A relationship can be long without being good for the people in it.
How can we check in as a couple?
A weekly check-in with appreciation, logistics, one concern and one request each is a simple method. It is a suggestion, not a clinical program.
What if my relationship is unsafe?
Success does not require staying in an unsafe relationship. Talk to a trusted friend, family member or counselor, and contact the National Domestic Violence Hotline at 1-800-799-7233.
Conclusion
What makes a relationship successful is less a single trait than a set of practices: honest communication, respect and trust, shared goals, teamwork, repair after conflict, consent and safety, and room for time apart and a wider circle. Research from Harvard and the Gottman lab links these with happiness, health and stability, though it cannot guarantee outcomes.
Define success together, check in weekly, and seek support if safety is at stake. Treat the keys as a conversation, adapt them to your own relationship, and drop whatever does not fit. Your next step is to ask your partner the three questions from the start of this guide and write down one goal you share.
