What is wrong with my husband?

He is punishing you in an attempt to teach you a lesson. He felt comfortable as the primary provider and feels that he lost some control to you when you bought the house. He could possibly have taken the stance that "since you made a decision like that without him, then you handle it." Everything seemed to be fine when he was in control of the living situation, income, etc. Now you have umed some of that control. He is being resentful and trying to "prove a point". If you don't do something about it now, he will ume that it will be fine to continue and things will only get worse. Give him an ultimatum: Be a man or things are drastically going to change. Don't whine or complain, you will be unconsciously hand over some of that control. Good luck!
