You need to cut all ties with her, delete her facebook , put all of her photos up, delete her number and her from your life.... You need to get on match.com, plentyofish, eharmony.com and MOVE on. There is a reason unknown to you now why the relationship failed however I promise you once you find someone else and fall in love again , it will be picture clear all the reasons it failed and you will look back and say , I sure am glad she left. Ask any guy on here this and they will tell you the same thing. Delete her from your life and listen , use this time to get in shape and work on YOU, then when you are not expecting it you will find the love of your life. Best of luck and if you need someone to talk to, you pm me my friend.
