My husband has turned to be the man I hated

A weeping  wrote,
I am a banker and got married to my husband about two years ago. Before our marriage, my husband and I had a true taste of love. I must confess he was not interested in sex in fact it was on our wedding night that we first made love. He was the dream man of women. We are blessed with a baby boy who is one year and some months. I am the hard working type which my my mother in-law testifies to that. I am glad to say she loves me so much but the problem is my husband has turned to be a different person. He has been a problem to me since he lost his job with and oil servicing company in Port Harcourt. He drinks like never before, shouts at me as if I'm a maid in the house and most a times, comes back very late. I have been the bread winner of the house since the incident and I have never complained. But what pains me is that he has turned to the man I hated. Please how best do I handle this.
