Man that's rough...I mean I don't know how you could ever have sex with her again knowing that every second she is thinking about the x piping her instead of you. Every time you are together all she really wants is for you to be him. She probably stays up every night trying to convince herself to just dump you and get it over with. You are not him, you will never be him. I give you credit for even having the stomach to look at her knowing you mean nothing to her. You could do anything and she would just toss you out like a half eaten bagel if it meant she could have just five more minutes with 'HIM'. I'll bet she cums harder just masturbating thinking of him than she ever could with you.
Good luck though man, hope it works out for you.
Man.. Thats harsh, n true. Yeah, as I said before, so long u are not into masochism, dont go with this road. You can get another girl, who will love u n not her ex.
If you think she's the only one, so be it.
Go n be masochist.
Or worse, go n be a gay...
Not that I recommend it tho.
It sounds hurt and...
gay.
