1. Forgiving her. Forgiveness for what? She did nothing to you, she doesn't need your forgiveness for her past nor do you have the right to judge what she did before you were in here life period.

2. on not answering about her past? It's none of your dang business, your business is what she is doing now and while she is with you. Period. what about this do you not understand?

Here is my take: She doesn't need to do anything to live up to your unreasonable expectations and she can't because you want some pure fantasy girl without flaw and she's never goign to be that whether she is upfront with you or not. It will only feed your fire of judgement and anger because she was not with YOU FIRST. Do you really think her teling you detalis about her past will make you feel better and why is that her responsibility? Hers is only to take care of what she is doing now and nothing in what you've said has told me that she's doing anything wrong now. that's what you need to look at, not her past.

I will be completely honest with you. SHE does not need to do anythng, YOU do. Get counseling about your extremely rigid and judgemental attitude toward people because your life is going to consist of people, gfs and otherwise that have "pasts".

Honestly I think you should let her go so she can find someone that will accept her as she is. and you can get help.
