No it's normal to feel like that when you have been betrayed before. But now you have to try and develop the trust with him cos if you cant then the relationship will be doomed to have alot of problems. And the problem is with you...
You say you feel disrespected and that's how you feel (nothing wrong with that)
I see that he needs to go out with his friends again and realize where he belongs. Trust me I'm sure the night will be BORING and he'll want to come home...he may not tell you that though. When someone is content in their relationship as your (man on the couch is) he'll be thinking about you...that's why I say go out with the girls yourself, give him something extra to think about
But relax honey, he knows who he wants to be with!
