Marriage issues

My wife has been provoking me lately. She's acting like she's tired of the marriage but doesn't want to leave. Late last year she hit an iron on my head. During small arguments she would lock my clothes and start biting me. I have sworn not to beat a woman in my life. Lately she refused to let me carry our baby; another time she intentionally left our 8-month-old baby's poo on my bed, which made me very upset when I came back from work. She refused to cook, but finished the stew and meat I cooked before I came back from work.
