How to know if they're the one: values, repair, and how you feel about yourself
There is no magic signal. But there are more reliable criteria than a gut feeling. Psychology and Gottman's research point to three concrete questions.
Gottman's research and attachment psychology point to three criteria more reliable than any "magic sign": value compatibility (are you heading somewhere similar on what actually matters?), capacity to repair (can you come back from conflict without destroying each other?), and how you feel about yourself when you're with that person. This last one — often overlooked — may be the most revealing: healthy relationships make us feel more ourselves, not less.
The myth of the perfect sign
Popular culture has built a resilient myth: there is "the one" and when you find them you will know it unmistakably. The sign might be a thud in your chest, an instant certainty, or simply "just knowing." Psychology has a different — and more useful — perspective.
Researcher Helen Fisher documented that the feeling of "this is the person" can largely be a neurological response to dopamine and norepinephrine — the same substances that make video games or sugar addictive. Not that the feeling is false; it's that it is not, by itself, sufficiently informative about the quality of the relationship long-term.
The good news: there are more solid criteria. And they can be observed before making major decisions.
Criterion 1: Value compatibility (not taste compatibility)
The compatibility that predicts long-term satisfaction is not about favorite music genres or restaurants — it's about deep values: do you want the same things regarding family, children, money, where to live, each person's role in the relationship?
Gottman's research found that couples who generate the most long-term conflict are those who differ on fundamental values without having discussed them before committing. Not because the differences are insurmountable, but because they were never named and each assumed the other thought alike.
Value questions worth exploring (and asking each other) before committing:
- Do we want children? When? In what context?
- How do we want to manage finances?
- What place does our family of origin have in our life as a couple?
- How do we want to handle major disagreements when they arrive?
- How much individual space does each person need?
These questions have no "correct" answers — they have answers that are compatible or incompatible with yours. And it's much easier to find that out before than after.
Indicators for evaluating the relationship (illustrative)
Criterion 2: Capacity to repair (not absence of conflict)
Gottman found that stable couples are not those who never fight, but those who know how to repair after fighting. The capacity for repair — returning to each other after conflict, offering a genuine apology, restoring connection — is a far more reliable predictor of a relationship's viability than the intensity of initial love or the absence of problems.
Questions to evaluate repair capacity:
- When you fight, can you come out of the conflict without open wounds lasting for days?
- Does either of you — or both — genuinely apologize? Does the other accept the apology without using it as a weapon later?
- Do you reach out to each other after a fight, or does each person dig into their position?
- Is there humor in the repair? (Gottman found humor in repair attempts to be a very positive sign.)
If most of these answers are negative, it doesn't necessarily mean the relationship is lost — but it does mean that repair capacity is an area that needs work before making major decisions.
Criterion 3: How you feel about yourself when you're with that person
This third criterion is the least cited in relationship guides and may be the most revealing. Psychologist Arthur Aron (New York University) developed the concept of self-expansion: healthy relationships expand our identity — they make us feel more capable, more curious, more ourselves. Unhealthy relationships tend to contract it.
Concrete questions for exploring this:
- When you're with that person, do you feel more energized or more drained?
- Is your life outside the relationship — friendships, projects, self-care — still functioning, or has it contracted since you've been in this relationship?
- Do you feel more or less yourself when you're with this person?
- Can you show parts of yourself you don't show others without fear of judgment?
Self-expansion doesn't mean the relationship is always easy or that there is never friction. It means the net balance — how you feel about yourself over time — is positive.
A relationship in which you consistently feel small, incompetent, anxious, or ashamed of yourself deserves an honest conversation — and possibly outside help.

Frequently asked questions
Can I know if they're the one before real problems come along?
Real problems are, in part, the test. But you can observe early signals: how they respond to frustration, whether they can apologize, whether your core values point in the same direction. Those signals appear before the major crisis.
What if I'm not sure?
Absolute certainty rarely exists and isn't necessary. What psychology looks for are signals solid enough to make an informed decision — not the absence of doubt, but the presence of evidence. Doubt is normal; persistent anguish may be a signal that something deserves attention.
Can someone change enough to become the right person?
People do change — especially when motivated and supported. But waiting for someone to become 'the one' based on their future potential rather than their present behavior is a high-risk strategy. Evaluate what you see, not what you hope to see.
