Jesse,

The fact that she's unwilling to tell her parents doesn't necessarily mean anything. I was in a similiar situation and I did not tell my parents the full story. I don't know the reason myself I just didn't want them to know. Very private issue for women.

What I think will be most effective is if you work on those issues, once you do, I'm sure that there will be a very sincere conversation with her about it. But I cannot stress enough that that converstation must come from real growth, not a desire to get her back.

I do not want to offer you false hope, but I was able to forgive, perhaps she will too, only time will tell. Use that time wisely.
