Kisi ladki ne mujhe propose kiya to main kya answer dun..

After the death of my parents my in-laws have been interefering in all my personal and family matters.Since I am alone and my kids are very small i am not in a position to take any decision. My wife also does everything according to her sister , brothers and mother. She always surpasses my wishes to fulfil that of her sister and parents. She taunts me for everything I do and does not leave any chance to humiliate me. She derives sadistic pleasure in insulting me specially in front of her mother, sister and brother. She threatens me indirectly to leave me and go to her parents and is also forcing me to go the the place where her parents are living. I have to take permission even for spending 10 rs. on myself. All activities at my place and even my bedroom is discussed with my in-laws. I am fed-up of all these and not in aposition to act properly at my workplace. this situation may lead to myself getting some sort of mental illness. Please advise
