I have been with my husband for seven years, married for two. Since the beginning of the relationship he has ?

cheated on me and blames me. I have always forgiven him and stuck by his side. Two years ago i noticed he began sleeping on the couch every night and when I would ask him about it he would say a lot of guys slep apart from their wives. We argued all the time about finances because I was paying all the bills, he would not take me out anywhere but he could hang out with his friends. And when he got upset he would destroy things in the home. When I was two months pregnant I came hoe from work one day and he had moved out, and I did nto here from him until two months later, when he called to tell me that he needed to move back home because he was having money issues. After I found out that he had called his ex-girlfriend a week before he left. I took him back , the baby was born, and he began sleeping on couch n basement again. Recently he came home for a party at 5:00am, when I asked him where he was he told me he was grown and did not need to answer to me and who did I think I was asking him questions. I told him to leave and he did so without an argument. I later found out that one hour after leaving he called the same ex girlfriend. Have not heard from him since, not even toask about the baby. Was it my fault for telling him to leave, would he still be here. I need help how can he leave and contact another woman right away, and not even give it time? Help
