All of what Robnew said....
It's also possible that she has other issues that you're not aware of....You would have to push hard to get her to tell you what they are though...I would wait until school is done with, though, if it's not.
I would imagine that she'll reach out when she thinks you want nothing more to do with her...women like us are messed up that way
I know you know that this is the most trying kind of relationship to be in. I do sympathize.
