play it over in your head for future references on how to deal next time this happens.
look for similarities and patterns in actions.
like i said in your thread during summer time, the second she started being rude to you and making it all about her, she had lost respect for you. she had already cheated at that point, or was destined to. learn to get out of a relationship when its bad, before it gets to such an extreme as cheating, resentment, etc. sucks though, because she had you by the balls, with the whole baby thing.
best of luck, hopefully you wont be such a cocky douche in the future. but dont let this turn you into a pussy either. your jacked and driven, things will work out.
