What should you do if your love of your life leaves you?

My boyfriend had left me, not to long ago. He said that the reason we are breaking up is because he couldn’t stand the fighting and he was always worrying. He would accuse me of cheating on him. He was very jealous and controlling. If a guy even looked at me with the “eye” he would freak out and think I was doing something behind his back. I would then cry to him saying that I love him and that I want him to come back to me. He would say “No I can’t because I can’t keep treating you the way that I have been and I can’t stop worrying about that you might be cheating on me.” Yes I did cheat on him once, but I learned my lesson. I LOST him. I have been totally faithful to him ever since. So now I’m wondering if he may be cheating on me. Should I not talk to him and wait for him to see that he needs me? or should I keep calling him and text messaging him? HELP! I want to be with him so bad!! He cries and goes on to other people saying “I want her back, I feel so bad about the way I’ve treated her!” But around me he’s like “I don’t even love you anymore.” I need HELP if anyone has been through this before or has anything to say write.
