You know OP, everyone will probably disagree with me here but thats probably because they're all misogynistic little bitches because they got their wee little hearts broke, but I think your kinda an ass. Yes, Jennys a fuckin ho for what she did, and I can say this being my family was torn apart because of a cheating parent. The thing is though, she is clearly sorry and truly regretful for what she did. Think about it: she has cried her fair share of tears and she fessed up even before you had to confront her. She took most of the blame for Carly's sake as well at first. She also tried to "lose" you, paranoid that you were following her, which suggests throughout the whole process she was riddled with guilt, and thinking about you. Besides, she knew that was wrong she just wanted to try something exciting and new, and after all, sex is sex, not love, she even wrote off the dudes already. Sure shes a ho and a piece of shit for what she did, but pobody's nerfect, people deserve at least one more chance at the end of the day, and if you really loved her, and I mean if you ever did, you'd give her a chance, otherwise I find it hard to believe what you had was really that special. You sound like the kind of guy, late 20's, who just gets married cause that's what you're supposed to do, and before it's too late. Be honest, you don't really love this girl, and you never really did. Also, she's more honest than you; she eventually told you the whole truth, and pretty fast at that, because she was clearly overwhlemed with guilt, meanwhile, you're still keeping the PI and these posts a secret from her. Why don't you continue to give her the cold shoulder for a while to truly drive it into her, and then try to forgive her for a second chance, maybe try some marriage counselling? You say revenge is petty? So is refusal of forgiveness. Make her let you have one free pass to cheat, boom, resolved. (Now I know that doesn't really resolve things, but as I already said, it seems to me that she is truly regretful and ashamed of herself, and besides, having have shared this story with unknown amounts of random and anonymous people is revenge enough).

Also, maybe you do have a huge penis, are insanely attractive, and filthy rich (despite what you say), all that doesn't mean you're any good in bed though, maybe she was dissatisfied. ;)

PS I think all the fucking Jenny/ Carly/ Zack jokes outside of these posts are fucking stupid and lame as hell.
