Somewhere between the last argument and the final goodbye, a strange question tends to surface: can this person still matter to me, just in a different way? It sounds simple enough, yet anyone who has tried it knows the answer rarely fits neatly into a yes or a no. There’s more nuance here than pop culture usually admits, and a fair amount of it comes down to timing, motive, and what each person actually wants once the romance ends.
Plenty of people attempt it anyway, some successfully, some less so. Before writing off the idea entirely or romanticizing it as proof of maturity, it helps to look at what actually happens when former partners try to stay close.

Staying in touch with an ex is far more common than most people assume. Research indicates that approximately 60% of people remain friends with at least one ex-partner. Among college-age populations, the number climbs even higher, with some studies finding that close to 90% of university students report being friends with their most recent ex.
Part of this comes down to how relationships form in the first place. A shared history doesn’t just vanish because the label changes. In reality, for many people, the story between two former partners doesn’t simply stop, it shifts, and the question of whether ex-partners can genuinely be friends is one that psychology has been grappling with for decades.

A well-known study out of the University of Kansas tried to map the psychology behind this decision instead of just assuming everyone has the same motive. They identified four reasons to stay friends with exes: Security, Practical, Civility, and Unresolved Romantic Desires. Each one predicts a very different outcome down the road.
Security means someone doesn’t want to lose the emotional support or trust the relationship provided. Practical usually points to shared resources, finances, or logistics that make full separation inconvenient. Civility is often about keeping the peace, especially in social circles. Unresolved romantic desire is exactly what it sounds like, and it tends to cause the most trouble later on.

Not all four motives lead to the same place. Staying friends due to Unresolved Romantic Desires resulted in negative outcomes, whereas staying friends due to Security and Practical reasons resulted in more positive outcomes. That distinction matters more than most people realize when they’re deciding whether to keep an ex around.
Longevity tells a slightly different story than satisfaction does, though. Staying friends due to Practical or Civility reasons resulted in the friendship being less likely to last in the long term. In other words, a friendship can feel fine in the moment while still fading out within a year or two, simply because the original glue wasn’t strong enough.

One of the more consistent findings in this area involves the order of events. A classic study conducted by researchers at Illinois State University found that ex-partners were significantly more likely to remain friends after their breakup if they were friends before beginning their romantic relationship. This pattern shows up again in more recent research too.
A study published in the Journal of Social and Personal Relationships found that exes who were friends before becoming lovers were better able to remain friends after their breakup. The explanation isn’t mysterious. Because the precedent of a healthy platonic friendship has already been set, the ex-partners are more likely to invest time into restoring the initial friendship.

Staying close to an ex rarely stays a private matter for long, especially once someone new enters the picture. Jealousy and suspicion are common reactions, and they aren’t always irrational. Maintaining a close relationship with an ex can seem unusual, or even threatening, to new partners, who may struggle with jealousy or insecurity.
There’s research backing up that instinct, too. A study published in Social Psychological and Personality Science examined how lingering attachments to ex-partners affect current relationships. The research suggests that choosing to remain friends with a recent ex can be detrimental to the new relationship. That doesn’t mean every ex-friendship dooms a new one, but it does mean the concern deserves more than an eye roll.

Breakups hurt on their own, regardless of what comes after. Research consistently links breakups to negative psychological outcomes including depression, anxiety, reduced self-esteem, and lower life satisfaction. Trying to build a friendship on top of that emotional wreckage, without giving it time to settle, tends to complicate recovery rather than speed it up.
There’s a bit of good news buried in the data, though. Large-scale panel research found that the dissolution of a non-cohabiting relationship led to a significant decline in mental health and life satisfaction, but the trajectories after dissolution suggest that the decline was only temporary, showing readjustment after 1 year. Interestingly, the same research found gender differences, suggesting worse consequences for men who experienced a significant decline in both dimensions and did not readjust in life satisfaction until several years after the dissolution. That gap is worth keeping in mind before assuming both people are healing at the same pace.

Jumping straight from breakup to best friend rarely goes as smoothly as it sounds in the moment. Emotions are still raw, and the lines between missing someone and genuinely wanting a platonic friendship can blur easily. In practice, this is rarely as straightforward as it sounds, since breakups are emotionally charged, and shifting from a romantic relationship into a platonic one can be decidedly tricky.
There isn’t a universal number of weeks or months that guarantees success. What matters more is whether both people have actually processed the split. Transitioning into a platonic friendship requires significant psychological work from both individuals, since the relationship doesn’t simply revert to a neutral state, it has to be actively rebuilt on different terms.

Some ex-friendships are friendships in name only, kept alive by habit rather than genuine platonic connection. A useful distinction researchers make is between simply being cordial and truly being friends. Staying on speaking terms is not the same as genuine friendship.
Watch for patterns like constant comparisons to a new partner, late-night check-ins that feel more emotional than casual, or a friendship that only seems to matter when one person is single again. Those are usually signs that unresolved feelings are doing the talking, not friendship. Given that staying friends due to unresolved romantic desires resulted in negative outcomes, this pattern is worth naming honestly rather than explaining away.

Not every post-breakup story is about loss. Some people come out the other side genuinely stronger, and that growth can shape how a friendship with an ex eventually looks. Research found that after a romantic breakup, people reported positive growth in their personal traits, relationship-maintenance behaviours, environment, and expectations of future romantic partners.
That kind of growth tends to make a later friendship healthier, since both people are relating from a more secure place rather than a wounded one. It also explains why some ex-friendships that seemed impossible right after the split turn into something solid a year or two later. Time alone doesn’t do the work, but it does create space for the work to happen.

The research points to a few practical takeaways rather than a single formula. Check your own motivation honestly before assuming your ex needs to change theirs. Give the friendship a real cooling-off period, keep new partners in the loop rather than hiding the friendship, and pay attention to whether the connection feels balanced or one-sided.
None of this guarantees a smooth outcome, since two people and their histories rarely behave predictably. Still, the friendships most likely to last are the ones built on genuine respect and security rather than leftover longing or simple convenience, exactly the pattern the research keeps identifying. That’s a more useful blueprint than most breakup advice offers.

Staying friends with an ex isn’t inherently wise or unwise. It depends heavily on why the friendship exists, how much time has passed, and whether both people are being honest about what they actually want from it. The research is fairly consistent on one point: motive predicts outcome far more reliably than good intentions alone.
If the friendship grows out of genuine respect rather than unfinished longing, it has a real chance of lasting. If it’s held together by habit, guilt, or hope for a second chance, it usually shows its cracks sooner rather than later. Paying attention to which one you’re actually building is the part most people skip, and it’s the part that ends up mattering most.
