Honestly, I think you take on too much of the responsibility for this relationship. I've only heard your point of view of course, but it sounds like you're doing all the giving.

She cheats on you.

Your trust in her is broken.

The relationship continues but you still feel insecure and jealous (but not to the point of jealous rages)

Your sex life isn't as great as you'd like it to be because she's not so that interested in sex.

She now doesn't like the fact that you're jealous but she doesn't want you to change for her.

*NEWS FLASH* - you've already changed because of her. You've become a more suspicious and insecure person because of her past behaviour ..... probably exascerbated by the fact that she doesn't get as enthusiastic about sex as you do.

If you were a woman I can guarantee that most of the advice-givers on this thread would be saying 'He's not good enough for you, girl-friend'.

Since I'm an equal opportunities busy-body, I'm tempted to say the exact same thing to you. I find it hard to believe that you are the one apologising and begging for a second chance here, when most people would say that it should be her. In cases where the trust is broken in a relationship, it is the 'betrayer's responsibility to earn back that trust, with the understanding that in some cases, it can never be regained. Sometimes, as much as you want to be able to trust someone again, you just can't. If that's the situation you find yourself in, you need to tell her that you need more time to rebuild your trust in her and that she needs to be doing more to reassure you. If she's not willing to do that, or you don't feel capable of rebuilding that trust, then it may be time to accept that the damage she caused early on in the relationship by cheating is irreparable.

She seems to hold all the cards in this relationship, and she's making you jump through hoops just for the honour of being her fiance. Tell me, is she really that wonderful? What is so great about her that you'd put up with being treated like this?
