Most Helpful Girl
Move on man. I think everyone will agree with me when I say most people here have no sympathy for cheaters. Don't play the victim card when you put your partner through hell by choice. I'm sure if she didn't find out you wouldn't be feeling this "remorse".
Move on, let her find someone who actually respects her, and try not to f* up next time you have a girlfriend

Think you should have tried and gone for a threesome with her instead of sleeping with some other girl behind her back. Too late now, once that trust is broken, it's very hard for them to give you a second chance anymore.
