Do Long-Distance Relationships Work? What Research Shows

Long distance has a bad reputation. People assume that without regular time together a relationship slowly starves. In New York, where people move here for jobs, leave for grad school and take postings in London or San Francisco, it's a question a lot of couples face.

The research is more encouraging than the reputation, with one important exception. Here is what four peer-reviewed studies found, including their limits.

Do Long-Distance Relationships Work? The Short Version

Across the studies below, the pattern is consistent:

• Long-distance couples report equal or better relationship quality than couples who live close.
• They are no more likely to break up while they're apart.
• The vulnerable moment is reunion, when couples who've been idealizing each other from a distance start living ordinary lives together.

That's a more useful picture than "long distance never works." Distance is not the main danger. The transition out of it is.

Are Long-Distance Couples Happier?

The largest study here is by Gretchen Kelmer, Galena Rhoades, Scott Stanley and Howard Markman of the University of Denver, published in Family Process in 2013. Using what they describe as a nationally representative sample of 870 people in romantic relationships, they compared people in long-distance relationships with those in close-proximity ones.

People in long-distance relationships:

• Reported higher relationship quality on a number of measures
• Reported higher dedication to their relationship
• Felt less trapped in it (what researchers call "felt constraint")
• Were similar to close-proximity couples on other kinds of constraint, the practical ties that make leaving harder

That last point matters. One reason people stay in relationships they don't want is that they're tangled up: shared leases, pets, routines. Long-distance couples, by definition, have fewer of those ties. If they stay together, it's more likely because they want to.

Are Long-Distance Relationships More Likely to Break Up?

Not according to the same study. People in long-distance relationships thought they were less likely to break up than people in close relationships did. By the follow-up assessment, though, they were just as likely to have broken up.

So the optimism wasn't fully justified, but the pessimism isn't either. Distance didn't raise the breakup rate.

An earlier study by Laura Stafford and Andy Merolla, published in the Journal of Social and Personal Relationships in 2007, went further. It found long-distance dating relationships were more stable than geographically close ones, but with a catch the authors put plainly: that held "as long as" the partners stayed apart. Once they became geographically close, long-distance partners were likely to end the relationship.

Why Do Long-Distance Couples Feel So Close?

A diary study by L. Crystal Jiang (City University of Hong Kong) and Jeffrey Hancock (then at Cornell), published in the Journal of Communication in 2013, tested this directly.

They followed 63 dating couples, 30 long-distance and 33 geographically close, for a week. Every participant logged each interaction with their partner, whether face-to-face, phone, video, text or messaging, and rated how intimate it felt.

The long-distance couples interacted less often per day. But on an interaction-by-interaction basis, they reported feeling more intimate. The researchers found two reasons:

1. They disclosed more. Long-distance partners shared more about their thoughts and feelings in each conversation.
2. They idealized their partner. Long-distance partners rated their partner as more disclosing than the partner's own reports supported.

Together, those two effects fully accounted for the difference in intimacy. In other words, the closeness was partly earned (more open communication) and partly imagined (a rosier picture of the other person).

Why Do Couples Break Up After Closing the Distance?

This is where the idealization finding becomes a risk.

Stafford and Merolla's 2007 paper found that longer gaps between in-person visits and extreme idealization during separation both predicted instability once couples reunited. The less often you see each other, the more room there is to build a version of your partner that real life will correct.

A companion study by Stafford, Merolla and Janessa Castle, published in the same journal in 2006, looked at that transition in detail:

• About half of long-distance dating partners make the move to living near each other. The other half break up while still apart.
• Among those who reunite, one-third end the relationship within three months.

Participants described what changed after reunion: losing autonomy, learning more about their partner (good and bad), struggling to manage their time, and more conflict and jealousy. The people whose relationships ended were more likely to say they missed aspects of being long-distance, like independence and novelty.

These are studies of dating couples, mostly young. They don't tell you the odds for a 32-year-old couple apart because of a job transfer. But the mechanism is plausible for anyone: distance can hide the friction that everyday life brings back.

How to Make a Long-Distance Relationship Work

The research doesn't hand out a playbook, but its findings point to a few practical moves.

Shorten the gaps between visits. Longer absences predicted instability at reunion. Frequent visits, even short ones, give you more real data about each other.

See each other on ordinary days, not just highlight reels. Long weekends where every meal is an event feed idealization. Try a visit where one of you works and the other runs errands. You want to know what Tuesday looks like.

Use the disclosure habit, then keep it. Long-distance couples talked more openly in each interaction. That's an advantage worth carrying into the next phase, when daily logistics start crowding out real conversation. Our post on how often to text when dating covers how communication rhythms shape early relationships.

Plan the reunion like a transition, not a finish line. Talk about how you'll handle time apart, friends and space before you sign a lease. Moving straight in together is a big change on top of a big change. Our look at living together before marriage covers what research says about that step.

Check whether you're idealizing. If you can't name anything about your partner that annoys you, you may not have enough information yet. That's not a red flag. It's a reason to get more time in the same room.

Is a Long-Distance Relationship Worth It?

If the relationship is good, distance alone isn't a reason to end it. The best available research says long-distance couples are about as stable as everyone else and often report higher quality.

What makes it worth it is having an end date. The studies describe couples who were apart for a reason, like school, and expected to close the gap. If neither of you can name when or how you'll live in the same city, that's the conversation to have now, the same way you'd talk about exclusivity once things get serious. And if you've just moved here and are weighing whether to keep a relationship from your old city, our guide to dating after moving to NYC covers what the first year here tends to look like.

The Bottom Line

Long-distance relationships work more often than their reputation suggests. In peer-reviewed studies, couples living apart report equal or higher relationship quality and intimacy and are no more likely to break up while apart. The danger zone is the reunion, especially for couples who saw each other rarely and idealized each other heavily. Close the distance with your eyes open and the odds look much better.
