Heh, well you could be the guy from Old School that flew home to surprise his girlfriend, only to find out that she was about to have a gangbang with like 5 other people...

Well, I can't say exactly what you've said, but I can say that one of my Ex's is now a lesbian with a girlfriend of over 3 years now, and she had to tell me over a fucking e-mail because she was too scared/nervous/apprehensive/etc. to tell me to my face...

That hurts, but that is different than the pure rage you feel over a cheat...
