Sex & the Single Woman: Between a Rock and a Bad Romance

As often as I find myself in awkward situations, this one is up there on the list.

One of my friends recently started dating someone, so I have slowly become friends with her. We aren’t super close, but close enough that we go on runs together and see each other a few times a week.

Unfortunately it sounds like they are breaking up, putting me in the awkward limbo of trying to figure out where I fit in the picture. I like her, but I definitely know him better. Right now I’m wondering how well you have to know the soon-to-be-ex in order for your friendship to survive.

Are there rules? Is it naive to think that any two people can’t overcome the awkwardness of the removal of a mutual friend? Is there any way to avoid taking sides in these situations?
