Need Serious Help

I'll start at the beginning. I met my girlfriend through who was my best friend. She was his girlfriend at the time but they were having problems and he had problems with addiction. She of course came to me to cry on my shoulder when they broke up 6 months ago. I fell in love with her and her ex moved a state away. Needless to say he is no longer my friend and I dont want anyhing to do with him. We grew in a relationship together and talked about marriage etc. She was in a constant lie with her family as to her relationships with anyone, and who she really is. She started to talk to her ex again and she told me she felt sorry for him. She lied to me and said she was going to one place but she really went to visit him. She came back crying to me and saying that they are over each other and that he just needed a friend. I found out a couple months later that they slept together while she was there. She is now telling me that she has feelings for him and she wants to move to be with him so that she can see for herself that I am the right person for her. I am worried for her to say the least. I dont trust her ex any further than I can throw him. I finally got her to talk to her parents and tell them everything. I even went to talk to them after she did to make sure they got the whole story and that they didn't think any less of me. They were very accepting of me and they are also worried about her moving. We finally got her to agree to see a counselor next week, but she is so set on moving. She is 19 and is so confused and as a result I am confused as well. She suffers from self worth problems. She was raped several years ago and word spread around her school and she lost her friends and her good reputation. Now when we go out she avoids people because she thinks she is ugly and she is worried about what people think of her. She s a gorgeous girl. Inside and out. She is what I want in a life partner. I hope the counselor will help her out but I am still very worried. She was going to move with no money in her pocket and get a job when she gets there. I offered her a good chunk of money so she could make it on her own and she accepted. Did I do the wrong thing? Could it be that she really has to go to decide what she really wants? Why can't she figure it out here since she knows us both already. She makes up things like how I am too good for her and she doesnt deserve me and I hate it. She is such a special person and I love her to death. At the very least I want the best for her.
