Divorce

I am rohit. sir I want to divorce my wife , as I can not get along with her. She and her parents are harassing me and my sisters. Her brothers have threatened me and my father twice . Now my father is dead and her parents have taken full control oh her. We have sent her to her parents house for few days as they asked us to do so. Now when she was supposed to come she declined to come and said that she will come 3 days later. In anger I told her to meet me in the court. She also agreed and now her parents are threatening us that they will file case against us for violence and dowry and get me and my mother jailed. She has kept harassing me and my family for simple things. She wants me to speak to her father daily on phone. If I don't do , she starts fighting. Some times she won't let me hold my daughter. I have no proof of all this. I stopped talking to her parents for almost a year. She says that I am torturing him but reverse is the case. She sometimes locks herself inside the room and threaten us that she will commit suicide. Sir me and my mom just want to end our life as we cannot bear this mental pressure. Our marriage is 21 months old. I know that Indian laws favors women. I don't want my mom to suffer all this. I am an officer in merchant navy and never asked for dowry. Her parents threatens that law will support their daughter only and me and my mom has to go to jail.She won't give divorce on mutual consent. Her parents have also said that I have to give him money and share of my property. They are all about money. As from the very first day itself my wife asked money, joint account. Sir i don't want to ruin my career and at the same time don't won't to live on my in laws terms. Please advise as I have no options left.
