Harassment and non children

Hi sir, my self zakeer. I got married on August 2020. This is my first marriage and for my wife this is the second marriage. They are my relatives.so, I accepted for the second marriage. Since from marriage time to till date there is no Menstruation from my wife. So, I asked to my wife about periods on October 2020. And she said she has a imbalance on menstruation. After a 5months we went to a hospital and the doctor told me that the size of uterus is small. So the doctor told me that there is 30% chance for babies. When I asked to her parents they are harrassing me and upon they created a bond and asking me to sign it. And I got to know from their relatives that she got already been treated from hospital and there is no more for babies. So, my family members decided and asked me to give divorce. My wife and her parents were cheated me on this. On a daily basis her father is harassing me. So, I decided to give a divorce for her. So, I want to know what type of case's that I have to file it.
