I dont know how much time has to pass before you can feel normal again, but for me, it was not long. I was ready to let go of the bad relationship for months before it was finally over. It sounds like bumper sticker philosophy, but I rather quickly picked up the shattered pieces of my life and moved on. I knew on an intellectual level that i was so much better off and that the resulting state of Happy would be forthcoming,and of course it did. I have friends now who are not users, manipulators, and just generally bad for my self esteem. Look for people who make younfeel good about yourself and don’t look back with any regret.
