I and everyone else who will post after me is going to tell you the exact same thing; give her space.. Not contacting her and giving her what she asked for will make her think twice. It might take a week or two, but wait it out, and when she does contact for the first time, ignore her and call her back two days later.
I'm going through this now as a matter of fact, but the woman I dated only lasted for 2 months and I was a rebound. I never felt used and I don't regret it because I actually like her. Anyway, I need to get the message across that I'm not one to be toyed with, and the best way to do that is to cut off all contact with her. Doing so gives me control of the situation.
