If she has really broken it off, it is going to take her some time to recover. Don't expect her to really be over it for a while. In the meantime, do some self analysis. Make sure that you are taking care of yourself. Be the best you that you can be. Don't let yourself be needy, or clingy. By being confident and comfortable with yourself, you will be more attractive to her, as she starts to come back. You don't have to make it easy for her, but you do want it to be safe for her. Don't be in a hurry.
