I just broke up with a good friend over the weekend. Long story short: She got a boyfriend, she got serious, she canceled on plans numerous times, and I needed Pals I could trust.

It was tough and we both cried, just like a real breakup. Which is why it makes me bittersweet to report on recent research from Oxford University that found that we tend to lose two friends every time we enter a serious romantic relationship.

Yikes! But also understandable, especially as we get older and our romantic partners aren't necessarily in the same social circle. When I get involved with someone, I try to make time for my pals, but some things: girls nights, Gossip Girl watching marathons, early Saturday spin classes fall by the wayside. I think the best thing is to make the concerted effort to see pals, but then also to realize that maybe your friendship worked better when you were both single.

I think that was the case with me and my friend. A large part of our friendship centered on the fact that we were single, and we weren't entirely happy about it. And I really do wish her the best. It's still . . . breaking up is hard to do!

Have you ever had a best friend breakup? And how did you keep friends when you got close to your partner?
