There are so many comments now I'm not sure you'll even read this but I know exactly how much pain you're in and I feel bad for you. My ex cheated on me too, not with escorts but with women he and I both knew. Coworkers, friends, moms from our kids school, even a teacher from the school. He said all the same things your guy said. He was sorry, he didn't mean it, it didn't count, he'll let me go through his phone, emails, Facebook etc. He said he'd go to councelling and that it wasn't his fault because he was damaged somehow. Long story short, he went to councelling once or twice then quit and I found out he was still talking to some of the women he had cheated with. When I was again angry about that, that's when he started blaming me for his behaviour. In the end I couldn't handle any of his bullshit anymore and I left him. Now, years later I see him doing all of those same things to every woman he has had a relationship with since. The worst part is he laughs about it to me. Its like he's proud of being a good enough liar to manipulate these women. He has no care in the world for their feelings and how wrong it is to intentionally hurt people like that. I know you're feeling horrible right now but be glad you found out now before you're married and have kids with this guy. You didn't do anything wrong, if he really did have these feelings of insecurity (maybe its my pessimistic nature but I suspect this is just an excuse for his bad behaviour) then he should have talked to you about it. The answer is not to turn to other women outside the relationship. You don't deserve to be treated that way and you sound like an awesome person, there are plenty of other men out there who are respectful and honest. That's the kind of man you deserve to have in your life.
