My husband behaves rudely all the time. Kindly advice.

Hello doctor,

My husband is mostly sad and depressed. He cannot listen a word against him or his family(mom, dad & sister). He gets mad and behaves very rudely with everyone if they do not agree to what he says. He fought with his boss in his company for silly reasons. He abuses me emotionally and mentally. He hides from colleagues and friends about his marital status, to some he says he is not married and to some, he says he is married, and his wife stays with his family and works in a bank (but I live with him and work in MNC). He always uses to tell a lie to me in small things also, he is never ready to accept his fault. Even if it is evident that it is his fault, he will never agree. He was flirting with some girl and went to meet her, and I got to know this when I checked his phone when I confronted him, he got mad at me. He is not ready to accept that he is at fault. He never answers my questions, always diverts the discussion. He does not have any plan. He hates my family for no reason and always say abusive things against them. He says he loves me but never let me live happily. In short, he is still right. Is he mentally ill?
