I feel your husband is resentful of you and wants you to leave him (thus, he treats you badly) so that he can get on with a bigger social life than he has had. He is in the mood to party so he wants to be free. The money has gone to his head and he now thinks he should 'share' himself around. But I feel he will fall in with people who only want to take from him. You would do well to be out of this situation.
