I got married 3 years back (arranged marriage). My husband is the only son to his parents. I live with my husband and in-laws. My mother in law is a mental patient. If she shouts at my husband & his dad, my husband takes her words seriously & starts fighting with her rudely like breaking things near to him or keeps hitting his own hands on the wall. My husband gets very upset by her words and gets angry. (knowing her mental condition). My father in law is tired of telling my husband not to fight with his mom as she is a patient. My father in law can't leave my husband and his mom alone at home and go anywhere. If my husband starts fighting with his mom, someone should be there to control him. Since my mother in law is a mental patient, she wants to dominate others. If anyone goes against her, she starts shouting and crying thinking others are neglecting her. All she wants is love. She gets jealous if I am happy with my husband because she thinks her son may forget her. So she is not happy with me and my husband's relationship. I didn't know all this before marriage, my husband should have told me about this before marriage but he didn't. I married my husband and all I want is to live a happy and peaceful life. I don't want any expensive things. My mother in law wants me to be with her all the time & she doesn't let me live with my husband. 1 or 2 days it's fine. I can not sacrifice my married life for her. I tried to convince her but she is not getting convinced. If she doesn't get convinced in this matter, she gets upset and starts shouting. If she gets upset, my husband also gets upset and starts fighting either with me or his mom. I don't know why. I asked my husband not to get upset deeply as I am his future too. He says "listen to my mom and do what she says, otherwise divorce me" if I listen to her, she will be in good mood and my husband will also be in good mood. To keep her in good mood, I can't sacrifice my life for her. If my husband doesn't get upset even if she gets upset or tensed, he will be in good mood and I can live a normal life with him. But I don't understand why my husband gets upset if his mother gets upset. He gets so upset by her words that he either becomes completely absent minded or starts fighting with her or with me very rudely. In that case someone should be there to control him. Can you please answer me, why my husband does so or would any man do the same thing as my husband?
