Your relationship has died. For many people the feeling of rejection, knowing their ex could be with them but just doesn't want to be, is actually harder than if they had died, especially if they're choosing to be with someone else. That's exactly why you need to decide you do not want your ex back. If you don't want someone, you can't feel rejected.

CHANGE IS A PROCESS. EVERYONE HANDLES GRIEF AT THEIR OWN PACE. BUT YOU CANNOT HEAL UNTIL YOU ACCEPT THAT IT IS OVER, AT LEAST FOR NOW. NOTHING CHANGES IF NOTHING CHANGES. USE THIS PAIN TO BECOME THE BEST VERSION OF YOURSELF.
Thinking about all the good times you shared is keeping you in pain.
♥ KNOCK YOUR EX OFF THAT PEDESTAL
Write a cons list (forget the pros), the biggest one is that he/she doesn't want you!
♥ STOP RE-READING TEXTS AND E-MAILS
You relive it every time you read it, and that's keeping you in pain.

shift your focus. take all that loving energy you're throwing at your ex and direct it inward. Create a new habit of taking care of yourself, emotionally and physically. You need to self-evaluate and decide you want someone better, and learn exactly what better for you is.
