Applied divorce - Wife denied for first night and have love affair

We got married on Aug 2018, She said not interested in first night now. So am not compelled her. But she is not speak well and not allowed to even touch her. The family members of my wife always brought to her in room and spoke with her so many times it happens regularly. I asked whats going on they are said like we gave normal advice to her. She is always alone in home. I too felt so lonely. One day i knew about her past she had lover and family knows everything they forced to get marry me. Am asked directly she said this are not true. After went to my home. She started to changed the behaviour. Hide the mobile phones and we sleep seperately and she said to act in front of your parents. They may be found we are not together. She always follow me to watch what am speak with my parents and started to do black mail if u tell anything to your parents I'll commit suicide. It goes on upto 12 days. After my parents found something is going on. i told everything to my parents they called her parents and told about misbehave of daughter. I got her mobile and saw the selfie with her lover. So i filed the divorce, but she wants to live with and asked to give chance. But i want divorce. So i submitted the evidence of selfie photos and after engagement of my wife call history and too evidence of first night not happened. Can i get divorce and without giving maintenance for her. She is also earning and her mom is teacher and her father is working too.
