This Is The No. 1 Reason Long-Distance Relationships End

Relationships can be trying even when you're in close proximity to each other. When you put a few hours between the two of you, those little everyday struggles just seem to amplify. Like anything else, though, if both you and your partner commit to putting in equal amounts of effort to make it work, long-distance relationships are doable.

The definition of "effort," and what couples look for in long-distance relationships, is changing, though. Success isn't necessarily keeping the fire alive in the bedroom, making sure you're in constant communication, or even taking turns making the trek to see each other. Smartphones, social media, and apps like Skype give long-distance partners easy access to their significant other almost 24/7, so lack of communication or even intimacy (hello, Skype sex) is no longer the big barrier when it comes to making a long-distance relationship thrive. So what is?

As it turns out, it might be the very same thing that can make any other relationship dissolve over time: failing to take things to the next level. According to one recent survey, long-distance relationships end when the relationship lacks a sense of progress.

Superdrug Online Doctor, a U.K. health service, surveyed 1,200 individuals across the United States and Europe who were either currently in long-distance relationships, had successfully made it through their long-distance hurdle and had since reunited, or had broken up with their long-distance partner. The questions focused on aspects like how they ended up in a long-distance relationship, ways the couple made it work, and reasons things may have ended.

In the end, while 91 percent of participants had given long-distance a try, 50 percent of those relationships failed. Interestingly enough, long-distance relationships that began that way had a higher success rate than couples who became long-distance due to circumstance. Things like not making an effort to travel, feeling sexually unsatisfied, arguing, and just the nature of growing apart definitely took their toll on the relationships that reportedly ended: The report found couples who survived through their long-distance phase spent twice as much money traveling as those whose long-distance relationships failed. More than 50 percent of the couples who survived also tended resolve their arguments more quickly than others, choosing to patch things up within a few hours rather than waiting until the next day or, worse, more than a few days later.

But the No. 1 reason long-distance couples decided to go their separate ways? Their relationship just wasn't progressing. A whopping 71 percent of women and 64 percent of men identified a lack of progress as the reason their long-distance relationship ended.

Relationships need forward momentum, whether the couple lives right next door to each other or miles apart. Is the relationship changing? Are you both growing, as individuals and as a couple? Monthly travel expenses, sex frequency, and arguments can be worked through, but if you and your partner stop making an effort to continue deepening your connection—by creating more emotional intimacy, learning more from each, and exploring more together as a couple—no matter where your partner lives, chances are it isn't going to work out in the end.
