I agree with outtolunch, trust your gut! If it doesn't feel right, its probably not. You are having a hard time trusting him because he violated your trust, he belittles your feelings. I can see why you don't feel valuble in this relationship. I'd be burned up too if I were you! But maybe its because I can so relate to how you feel, being betrayed by him. All I can say is don't bury your feelings, don't deny them. You don't have to react to them, but they may be telling you a message, a warning. You clearly don't feel this person has your best interest at heart. Make sure YOU do.
Take care of yourself.
