That is a MAJOR crappy thing to do! Once, when I was "desperately single" I had a serious crush on one guy named Jim (how cute, huh? Jim and Kim?? ) and once I found out he had asked my best friend out, and she said no (thank goodness) I was no longer interested in him at all. The way I looked at it was that she knew how I felt about him and she respected that enough to say no, and in turn, I no longer wanted him because he wanted her more than me and I refuse to date anyone who doesn't choose me first. I know, I'm weird that way (I feel it like a guy that dumps you then calls back a few months later to get back together... if you didn't want me once, why would you want me again?) But I digress.... my situation was a bit different because you and he didn't have a chance to find out what could have been before he asked your best friend. I think friends should always abide by the "no date ex-BF EVER" pact.

Another story (on a junior highschool level) my daughter learned early this year to NEVER EVER date a friends ex no matter what she says, and no matter how long they dated, no matter how badly they split up! She dated her on friend's ex (we're talking 8th graders here, so they REALLY had SUCH a history together! They dated a whole 2 weeks! ) and this poor kid harassed my daughter every day. She called 15 times a day to see what my daughter was up to. It was VERY annoying, the jealousy. My daughter broke up after an equally long time of dating the same boy and the friendship has never been the same since. We told her before she started dating the boy to not go there, despite what the friend said (she said it was ok... duh, it wasn't!) She now knows to not even THINK about another friend's ex.
