Divorce

I am from tirunelveli. I am I got married 2019. Myself and my wife staying together at present. My wife is not willing to stay together, but she is forced to live with me by her mother. My wife always mentally tortured me to give divorce. Secondly, she always abuses me that I am not worth, orphan and financially zero. Her mother also blackmails me that if we both not staying together she wolud commit suicide. Because I don't have father and mother and told my financial condition to wife's family before my marriage. Though she and her family knew my situation she abused me. For sake of her mother she is living with me, not with true intuition. I lost my interest to live with her. In this worst condition I am not able to focuse on my career. I am personally worried about my future also. Her mother and she is also not letting me live alone. Several times I requested my mother- in law to take her to their house for time being. They are not even doing that. I don't have any moral support also to speak to her family. Day by day I am becoming mentally ill, sleeping sickness and some times feel chest pain. Now I would like to face this situation legally and finally divorce.
