Stay friends after being cheated on?
I was friends with this guy and then we started dating. I knew he had been dating another girl but he supposedly had dumped her and started dating me. 3 months later he went on a trip with a group of friends and he cheated on me with the girl he had been dating before me. We became "friends" again, but he started drifting and now he's gotten serious with this girl. I really can't stand seeing them together but he insists it is immature of me if we stop being friends, because 5 months have already gone by and because he really loves me as a friend. What should I do?
