+1. Couldn't agree more. Hit the gym hard and run, you'll feel much better about yourself. Completely ignore her no matter what. Lose her number and block her on any social networking sites. The more you keep away from her the easier it will be. If she hits u up wanting to talk about things or fuck or argue, ignore it completely, don't answer back at all, not even to call her a whore.
And lots of alcohol and sluts.
