Close the chapter of your life in it and go in, which I don't think you've been able to do, even with dating other people. Use this time to find new activities, work out more, get in contact with those friends that you haven't seen. You might be surprised.
Takes a little time to rebuild a person after getting stomped down, and it's not easy...
But keep this in mind, think of who she is now, telling folks they you were hitting her... err wtf... really ;/
Best of luck
