Wife and her family threatens to file a case against her husband and in-laws

My wife has been threatening me to file a case me and my family members. My wife and her family members have been threatening me of filing a 498A case, involving mental and sexual harrassment. I am living with my wife in a rented house and my parents are living separately as my wife does not wanted to live with them. In fact, last year, my in-laws has forcibly taken a written consent from me on a stamp paper that I am leaving my parents house as they have mentally and sexually tortured my wife. I went to take my wife from her home wherein they forcibly made me write this on a stamp paper that "my parents sexually and mentally harassed my wife and due to her safety, I am leaving this house". They made me write this and took my thumb impression too. A few hours later, I was taken to a hospital because I was in a semi-conscious state after they made me to write on a stamp paper. I am presently living with my wife in a rented house from the last one year and none of my parents have visited my house or have contacted my wife from last one year. Kindly, guide me as my wife and his family still threatens to file a case me and my family.
