Forget the Red Flags - Ask Them to Tell You the Story of Their Last Three Relationships

Dating culture has become obsessed with flags.

Red flags. Green flags. Beige flags. Lists of behaviors supposedly capable of telling us whether someone will be a good partner before we've even finished the appetizer. I think there is a considerably more interesting source of information sitting right in front of us: the person's relationship history, and especially the way they understand it. I'm not suggesting that somebody with several failed relationships is defective, that casual sex predicts infidelity, or that divorce should count against somebody. Plenty of decent, emotionally healthy people have complicated histories, and sometimes a relationship really did end primarily because the other person behaved terribly.

What interests me is the pattern across the history. Research gives us good reason to take that seriously. One longitudinal study followed people across two successive romantic partnerships and found eventual stability in five of seven relationship characteristics studied. Relationship and sexual satisfaction, perceived instability, conflict, and intimate exchanges showed substantial continuity across partners. People generally experienced the predictable honeymoon-like improvement when entering the next relationship, but many characteristics began drifting back toward familiar territory as that relationship developed.

An earlier longitudinal study reached a related conclusion: relationship quality, conflict, and even abusive experiences showed meaningful stability across different partners, with stable individual characteristics helping explain some of that continuity. A huge meta-analysis involving 148 samples and more than 153,000 participants also found substantial stability in individual differences in relationship satisfaction over time.

That doesn't mean your past determines your future. It means changing partners doesn't automatically change the person you bring into the partnership. And that makes somebody's romantic history more interesting than simply counting exes. I would want to know how their relationships formed. Were they intentionally choosing partners and building relationships, or did relationships repeatedly emerge from ambiguous arrangements in which commitment was never clearly discussed?

Were most relationships affairs, hookups that drifted into something more, friends-with-benefits situations, relationships entered because somebody was lonely, or partnerships that seemed to happen because the other person pursued hard enough? None of those beginnings automatically predicts disaster. Friends-with-benefits relationships themselves are far more diverse than popular stereotypes suggest; researchers have identified multiple distinct forms, ranging from genuinely friendship-centered arrangements to primarily sexual relationships and arrangements attempting to transition into romance.

So I wouldn't treat “I've had friends with benefits” as a red flag. I'd become interested if every important relationship seems to have been structured around avoiding clear commitment, tolerating ambiguity, keeping alternatives available, or allowing somebody else to make the relational decisions. The clue isn't the category.

The clue is repetition. The same principle applies to endings. Ask someone why their last several relationships failed and listen carefully. Not because you're interrogating them about their exes, but because you're learning how they construct relational reality. If every former partner was crazy, narcissistic, controlling, jealous, emotionally unavailable, abusive, selfish, immature, or incapable of appreciating them, perhaps they have simply endured an astonishing run of terrible partners. That happens.

But if you hear the story of five failed relationships and cannot locate the speaker anywhere in the causal chain, I would become curious. Relationship science has studied attribution for decades because the explanations people construct for relationship events matter. Longitudinal work has found that how partners attribute responsibility and causes for negative relationship events is associated with later marital satisfaction. Large longitudinal research also shows that conflict behavior matters over time: more frequent conflict and withdrawal, along with fewer constructive behaviors, predict poorer subsequent relationship perceptions.

That doesn't mean healthy people blame themselves for everything. In fact, taking responsibility for abuse inflicted on you would be a distortion in the opposite direction.

I'm talking about something subtler: the capacity for self-observation. Can somebody say, “She betrayed me, and that was her responsibility, but I can also see that I avoided conflict for years”?

Can they say, “He was incredibly controlling, but I ignored obvious incompatibilities because I was terrified of being alone”?

Can they recognize, “I kept choosing people I needed to rescue”? Or, “I became defensive whenever she criticized me”? Or, “I stayed long after I knew it was over and became resentful instead of leaving”? Or even, “I treated someone badly back then. I understand why now, but I wasn't a good partner.”

Those answers tell me something very different from a spotless autobiography in which the storyteller has somehow been the innocent passenger in every relational catastrophe they've ever experienced. Because the question isn't whether somebody has made mistakes.

The question is whether experience has produced reflection.

Attachment research adds another layer. Longitudinal studies suggest that attachment security and insecurity can predict aspects of later romantic functioning and relationship quality, although relationships themselves can also change us. That bidirectionality matters because we shouldn't reduce people to an attachment label, but we also shouldn't pretend that every new relationship begins on psychologically untouched ground. We bring ourselves with us.

Our conflict habits come along. Our expectations about intimacy come along. Our comfort with commitment comes along. Our beliefs about sex, loyalty, autonomy, jealousy, dependence, honesty, and repair come along. So do our methods of choosing partners and the explanations we construct when relationships fail.

A new partner changes the equation enormously, but they don't erase everything already written on one side of it. This is why I think people sometimes misunderstand what it means to “not judge someone by their past.” You shouldn't condemn somebody to their past. But you'd be foolish to pretend it contains no information. The relevant question isn't whether somebody has a pristine romantic résumé. Frankly, at a certain age I might find that its own kind of interesting. The better question is whether you can see development across the résumé.

Did the person learn anything? Did their partner selection change? Did their communication improve? Did they become more intentional about commitment? Did they learn to tolerate intimacy rather than repeatedly chasing intensity? Can they identify what they did when frightened, angry, jealous, bored, rejected, or dissatisfied? Can they distinguish between what an ex genuinely did to them and what they themselves contributed to the relational system?

Most importantly, does their current behavior provide evidence that the lesson actually took?

Because insight is cheap when it remains autobiographical storytelling. Someone can give you an extraordinarily sophisticated explanation of why every previous relationship failed while currently doing the exact same thing to you. That's the part I'd watch. If they tell you every ex was controlling, what happens the first time you establish a boundary?

If everyone else was jealous, what happens when you raise a legitimate concern about another relationship? If every previous partner “couldn't communicate,” what happens when you say something they don't want to hear? If they claim they've finally learned to choose healthy relationships, what happens when stability begins feeling less exciting than chaos? If they say they've changed, you don't need to prosecute their history to determine whether that's true.

Watch what happens when the old conditions reappear. That, to me, is much more useful than collecting red flags. Human beings absolutely can change. Personality develops, attachment can shift, relationship experiences teach us, and people sometimes do extraordinary work between one relationship and the next. The past should therefore be treated as data, not destiny.

But data still deserves to be examined. I don't particularly care whether somebody's romantic history looks messy. Life is messy. What interests me is whether the mess contains the same architecture over and over again: similar partners, similar beginnings, similar conflicts, similar exits, similar villains, similar explanations, with one remarkably consistent person appearing in every story.

Because eventually there is an uncomfortable statistical fact none of us gets to escape:

You are the only person who has been present in every relationship you've ever had.

That doesn't make every ending your fault. It does make your patterns worth knowing.

And before asking someone you're dating whether they're a red flag or a green flag, I might ask something considerably more revealing: “When you look across your past relationships, what do you think you kept bringing with you?” The answer may tell you far more than the flags ever will.
