I dont want my boyfriend to talk with other girls?

That right there is completely wrong. I would have broken up with him a long time ago. Considering that he did all that behind your back and tried stuff with other girls AND had a relationship while you two were dating is unbelievable. You don't deserve that at all, he's not loyal. I'm saying this because what you just typed up there is messed up. Don't be with this guy.. as much as you trust him now..it's not right.
