I'm having the same problem about not letting go and nothing has worked at all. It doesn't sound like u were in love tho, it sounds like u were insecure n he played on that making you more insecure. He knows exactly what he did to you and these other women. He is a manipulative loser. Honestly I would confront him n tell him how horrible and rude he is. It will make you feel better n hopefully help you move on. Just tell him everything on your mind so it's all out n u don't have to waste another minute of your life on him.
