My father was abusive growing up. He was an alcolholic and beat my mother and me. Growing up I swore I would never end up like my father. He was a bastard and I hated him. Now I'm married with a 3 year old daughter. Our marriage is on the rocks right now. We have a hard time paying bills, ect, and it makes our marriage more stressful. I was drinking alcolhol watching the football game a couple nights ago when my wife walked in angry. She was mad that I was relaxing after a long days work and that I wasn't taking care of our daughter. (Wife works till 2pm, picks up daughter from daycare, cleans house, ect.) she was yelling at me and it pissed me off, i work hard to pay for our home, bills, clothes, ect, and I was feeling unappreciated. Well....I slapped her. I feel bad, and humiliated. I can't look at myself and feel good. I'm turning into my father. My wife took my daughter and drove to her parents to stay the night. She said she won't come home. What can i do?
