Help he cheated and now I become to controling how can I stop?

Your not "become to controlling" you trusted him he broke the trust, its normal to be suspicious. He's the one suppose to make it up for what he did, he's the only one can fix your suspicious problem, if he doesn't and acts like nothing then the relationship might fall apart.

Trust is key in a good relationship and he destroyed it whether you forgave him or not. You're not being controlling, you're being suspicious, and for good reason.

I'm not going to say anything in regards to whether you should leave or stay, but if he's accusing you of being too controlling, then he's not mature enough to be responsible for his action.

Omg I'm in the exact same place as you. I trusted my man with all my heart. I had no reason to doubt him. Then BOOM he cheated. And now anything he does and everything he does I feel the need to know. I don't believe anything he says to me anymore. And the worst part is. I think he can change.

Just because you forgive someone doesn't mean that you magically start trusting them again. It's really hard to trust a guy again after he has cheated on you. And there's good reason for NOT trusting a guy who has cheated on you -- the odds are that he'll do it again!
On the other hand, a relationship without mutual trust is going nowhere. So what's a girl to do? I think you need to think long and hard about this guy and about your relationship. Do you really believe he learned his lesson and won't cheat on you again? If you really believe that, then give him your trust, and the benefit of the doubt. Don't make him prove he's innocent all the time -- assume he's innocent until you have proof that he's not. But if (as I suspect) you DON'T really believe he will be faithful, and you are NOT able to trust him, then start thinking about how to end this thing, 'cause it isn't going to work. Good luck!
