Go to the wedding and **** her sister.....or mother

It's probably just a courtesy in case her parents liked you. I'm sure she doesn't really expect you to show up.

Don't go, she wants you to go because it will reassure HER that YOU'VE forgiven her! It's all about making her feel ok with herself regardless of how you actually feel about her adultery.

Go for the free food and hire a model on line to come as your date and shower you with affection.

Wedding Crash that ************!!!!!

At least it means she didn't leave you in vain. She obviously actually loves that person, so at least she didn't cheat because she didn't love you or whatever. I personally would find that slightly reassuring, as awful as the situation is, that she did it because she had to, not because of you. Still, not to take away from how hard it must have been of course. Surely it'd be worse if she did it for someone she didn't give a **** about rather than someone she'd want to marry?

Open bar? I say go, make an ass out of yourself, and ruin her wedding. Be sure to repeatedly point out that she is a cheater and a liar.

I'd have about a million things to say in that situation.

Tell you don't ******* care if it means anything to her! She obviously didn't care about your feelings when she cheated, and doesn't care about how you would feel about going to her wedding either... ******* bitch, is nobody faithful anymore?

Come with a supermodel in a white dress.
