I so much want to ask her what the hell she wants??? I mean why hang with me if you have no intention of fixing things.

What I see in your post is you being the antagonist. You probe, you assume, you end up defending yourself. That's all great if you wish to reinforce walls.

Let go of that thinking. It only adds to your pain and frustration. Why hang with you if she has no intention of fixing things? Why is that the question? She can't hang with you unless that's the motivation? Maybe she still enjoys your company, just doesn't wish to be in a relationship with you right now. "Fixing" the relationship is probably the last thing on her mind, for to fix it would mean she'd be with you. She's not on that page. You are.

Instead, why not accept that she still finds your company attractive to some degree and use those opportunities to make her even more comfortable with your company instead of opportunities to quiz her to satisfy your puzzlement, which only makes her uncomfortable and guarded around you? How would you inter-act with her if, let's say, she was the new girl on the block you were interested in? Put on that mind frame.
