When you and your bff like the same guy?
Well The Joker comes into the room and breaks a pool cue stick and says we are having try outs but only one of you will win.
Anyway's I wasn't aware your BFF liked me. <_>
But really, I have no idea. I would suggest just getting together with him and talking it out as a group. It may be that he might not want to date either of you. If he does then the other girl needs to learn how to handle loss maturely and not go all Mean Girl's.
A guy should not get into the way of a friendship...unless he is Uber-hott, then you have a problem.
But really, why no see who the GUY likes...
I say wrestle in a cage match to the death jkjk
Anyway this did happen to me and a friend once. We got into a big fight over it and didn't talk to each other for a couple month until the girl that we were fighting over screw us both and then we made up in a non gay way...
