I know that feeling well hope That happened to me earlier this year. Time for you to do a 180 on her and if she wants to come back again, make sure that a lot of time has passed. Use this time to work on yourself and change yourself for the better Go out and enjoy yourself, catch up with old friends, join support groups, do anything that shows her that you're having fun without her. If she does change her mind in the next few weeks, then start dating her again. Ask her to come to counselling with you or mediation. The last thing you need right now is her yoyoing backwards and forwards. I know, this has happened to me as well and trust me it's not pleasant!
