Divorce

I was married in 2015 . After marriage I started living with my wife in another city in rent. But in 2017 I came to know that my wife have a affair with someone also got that tym call records. That tym I forgive my wife. In 2019 we become parents of a girl baby. But at a same time of having baby girl when she was just of 3 days I again caught my wife having what’s up chat with same guy . That tym I told to her and her parents that I cannot live with her as she continuously cheated me. She ruined my faith nd trust also she has no mercy that she is having a baby of just 3 days , it means when I caught her first tym in 2017 after that she was continually with someone else . This all cause me as a mentally disturbance. Now I told her that I don’t want to live with her and I want divorce form her . But she always deny to give me divorce. Also in 2017 just after 1 month of having child , when I told her that I dont want to continue our marriage, she instead of felling guilty she file a FIR against me nd my mother blaming for dowry nd violence. That tym I was upset nd was not in a sense that what to do. Also after filing FIR , she went with me in my house . I called her mother and Brother to tell them that what she have done. Also I called sarpanch ( leader of my village) in front of them to told that about her, there in the presence of he mother , brother nd sarpanch she admit her mistakes nd also admit that she have filed a false FIR against me nd my mother . But that was not end she continuously go ahead with same behaviour also now these days she asked to me and my parents not to enter in the house also her mother demands for 15 lakhs for mutual divorce. But I am unable to have them this amount, so In the end don’t want to live that lady . Also I want custody of child too coz I can’t let my child to stay with her as I don’t have faith upon her and her family too , because they may hurt my daughter or can do anything with her. So pls suggest me what to do in this situation.
