Be honest with her. Tell her everything that you're rambling on here about, but in a much more concise and gentle fashion.Sabiancym said:snip
Tell her that you're hurt and confused and you need to know what your relationship is and what it isn't so that you can have peace about it.
Tell her what she means to you: that you care about her and want to be with her, but only if she's comfortable being with you.
Ask her what she wants from your relationship. Does she want to be your girlfriend or not?
Based on my experiences, it's likely that she doesn't know what she wants. She probably has trust issues (most abuse victims do).
I'm betting one of three things:
1) She would be interested in you, but isn't allowing herself to develop strong feelings for you because she's scared. In the beginning it was easy because it was all passion neither of you really had to think about what it all meant. As the relationship started to get more real, she distanced herself because she's scared. She's going to need time and understanding before she can get past her fears and be in a healthy relationship.
2) She was using you. She likes you as a friend but also used you for sex/comfort, and now she just wants the friendship, but no sex/romance. Brace yourself for that possibility.
3) She was afraid that you were using her. Like you said, you two never made it official that you were in relationship. Since she's been abused in the past, and you two slept together so soon, she may be worried that you're only interested in her because of the sex and you just want to use her to get what you want (which she has likely experienced from guys in the past). Therefore, she's distanced herself until you step out and say, "Hey, I want something real with you because I really care about you for you, not for what you do for me." This could also explain why she's been telling you about other guys hitting on her AND telling you that she's not interested in them. It could be her way of saying: "Hey, no more casual sex/kissing. I want to know honestly if you're really into me as a whole person or not. And it's not like I don't have other options, but I'm not interested in them because I want to know exactly how you feel about me."
(All three of these could be wrong, so don't be surprised if it's something way different. I'm just talking from my personal experience and my pattern recognition.)
You have to talk to her. It's unhealthy if you don't.
If she's interested in starting a relationship with you, congratulations.
If she's not at all interested, it'll be tough, but at least you can know where you stand and move on.
If she doesn't know what she wants or says that she needs more time then tell her that until she figures what she wants you two will just be friends. You seem very emotionally invested and if she doesn't know what she wants you DO NOT WANT to let yourself be strung along waiting for a resolution. Trust me. I've been there. It sucks worse than anything else I've experienced. If she doesn't know what she wants than you need to distance yourself. Be her friend, but don't pine after her waiting for her to come around. That will tear your heart up, my friend.
Just talk to her. Be gentle, but honest. And good luck.
