Geez, if you want an advice so badly, here it is; Don't. She might have emocional issues, and you are too anxious. If you guys get together now, it might end up in failure due to thje rush. Wait for her to breakup on her own (Because, you know, when you are in a bad reationship, you don't need to be with someone else in order to break up), and let her know that you'll be there for her, until both of you feel like you are ready for the next step.

Boy, you sound like 15.
