I agree with hankster that your insecurities are not caused by you knowing about her past. You are just insecure. If she has been faithful to you in this relationship and not running around on the side, then there is nothing she needs forgiveness for. She made a mistake giving you so much information, but it seems her past is known in the circles you guys travel in, so I suppose it had to be talked about.

It sounds like you're in love with each other. That is what is relevant to now. Stop being ashamed of having her for a girlfriend. Be proud that she is overcoming a pattern that was probably very unhealthy for herself. Meeting you seems to have changed her life in a very positive way. You can be proud of that.

If the two of you decide to stay together, then you both need to close the door on her past history. She needs to wise up and stop giving you details that you do not need to hear. That is not being "honest," but just silly and stupid. It sounds like her teenage years were very troubled, and she deserves credit for growing past the pattern that she was in . . . . if that's what she has done.

You running around jumping into beds to try and even some score sounds a lot nastier to me than the fact that she had a troubled past. It's good to want to understand your partner. In that sense, try to find out what was so negative in her years from 14 to 22 that had her that desperate for a form of attention that was could not possibly have been very satisfying.

Really, the main question now is: do you deserve her?
