Best friends are the ones who are with us through thick and thin, through coming and going romantic partners, through just about everything. But for some reason, best friend breakups don’t get as much attention as their romantic counterparts. Why? They’re just as devastating, if not more.

It sucks, but like any other breakup, it can be for the better. We spoke to 15 women to learn more about how and why they broke up with their best friend (and vice versa).
