I need some advice. About a year ago I found out that my girlfriend had cheated on me. Two weeks ago we broke up, and I won't go into details suffice to say that we are still friends. Now a close friend of mine is having a party to celebrate his 21st this weekend and both my ex and the guy she cheated on me with will be there. I was intending on just not going, as I'm kind of worried that I will do something stupid and I don't want to screw up the night. But I know that my friend will be extremely dissapointed if I don't and it is a special night for him. So I've been thinking this through and I still don't know whether or not to go. I'm wondering, has anyone else been in a situation similar to this? How did you handle it and what do you think I should do.
