OK so a few months ago I met a girl who I really like and I was attached to and everything was going good til I found out she was cheating on me. She realizes she is falling in love with me and dumps the other guy and will never cheat on me again because I'm the first guy she has ever felt real love towards. But the problem is, after I found out she had cheated on me I lost all attachment so I feel absolutely nothing. Even when we're having sex I still feel no attachment towards her. I have decided to stay with her partly because the sex but also partly because I enjoy 'having' someone. (And because I'm a pansy who has only broken up with 1 girl) But there is a very attractive girl at work who has wanted to hook up with me for a long time, she knows the situation with my GF and is still willing so I'm thinking about having sex on the side with her or at least hanging out with her and I'm already hanging out with an EX who also knows the situation. Don't get me wrong, I am normally a nice guy who would never cheat on a GF but she cheated on me and it really pissed me off, I know 2 wrongs don't make a right but this has really changed my opinion on relationships. When we were first together I was the one who wanted us to last and I really thought we'd have a serious relationship then she did what she did and I lost all interest but now she feels the way I did at first (plus more).. My friends all are saying to stay with her because most of them have gone through similiar things and they said the attachment comes back.. Opinions?
