Jillian, I think you need to lay this one to rest. It sounds like you holding your heart out to her and she doesn't know what to do with it. I don't know you're history with her, but I'm guessing things have been said on both parts that have hurt both of you, and when feelings are raw like that it is natural for the heart to shut down in an effort to protect itself. In your case you are pleading for more, she is afraid to give anymore and doesn't see why she should, despite the fact that she said she wanted to be friends. I'm guessing she thought being friends would be easier, but she is feeling guilty about you and can't deal with it.
It's a lot easier said than done, but I think you need to stop seeing her, put some distance between you and start looking after yourself. Being with her will just keep reminding you that she and you are not together anymore. At the moment it seems like you are evaluating your worth based on how she behaves towards you. I'm sorry to say it, but I don't think she is going to change her attitude soon.
You can't control how she feel, thinks or acts towards you. You are the only one who you can control. Take control of your situation - the only way you can get out of this is by controlling your own actions and moving away from this.
It is very hard to do, but it is the only way. I have recently come out of something which I think is similar to where you are now.
