I want a divorce after 6 months of marriage

Hi, My Name is Sagar, I got married on 22 April 2022, let me just clear I was forced to marry by my family. I was in love with a girl who was not our caste and my family wanted me to marry in our caste so they blackmailed me by saying they will die and forced me to marry the girl they like.. and I agreed beci they were giving death threats. But it's been 6 months and a lot has happened, my wife is a housewife and she is not earning but she is give me mental trauma, and I just can't continue with her.She knows about my past so she keeps nagging me about it and keeps doubting me and blames me that I cheat on Her but I donot .because the girl I loved left me. She makes small arguments big and threatens to kill herself, one day she even hold a knife to her hand threaten to cut herself, she sometimes slaps herself during argument & cry, she keeps saying that just give me one child and I will never let you touch me again. Im mentally tortured & she is a selfharming person & I want a divorc
