You need to respect her decision, cuz there isn't really anything you can do. Give her time, and don't chase her. Please just focus on yourself, and do things that are good for you, and makes you happy. If there is a chance she is going to take you back, then that is probably the only way anyway. If you are happy and enjoying life, she will notice, trust me.
Be the strong one. Be the one that can find/deserves someone better. Be the desired one.

I'd recommend being best friends. Being best friends means your just out of being in a relationship. And your closer than any other guy if you are to her. You'll still be able to talk heaps and at least you'll be there. This gives you the highest chance, trust me. If you try push in and get her back, she's already stated her opinion, and might push you away completely
