Marriage Disturbance With my Wife.

Dear Sir, I am into an unbearable situation. I got married in Jan 2019 to govt employed wife (Postal Dept). I am also working in private company. Her income is more than me. After my marriage, she is not listening my words and don't loves/take cares of me. And she also neglected my father & mother also. In any small issue in my family she call her father for interfere. After her father come he also misbehave to my family. After 6 month of marriage i know that, she is talking with her boy friend (Having phone call details/bills) more times with absent of my knowledge. I say all the details to her parents in front of my wife, but her family don't say any things to her daughter. She is attempt to suicide in my house one time. Now she is staying with her parents last 1.2 years. My family have tired to talk with her but her father don't allow for talk. And he say that, what will happen you wait and watch and we will see in court. After that issue their are no contact with each other. I have doubt she may be change her phone number any that boy also change his phone number. After that she may be talk with him. Due to this reason my good relation have been broken. Now everyone is silence. My questions are: 1. Her father threatening me we will see in court, if he do that what happened. 2. I want divorce but she refuse that she not come to my home or not give divorce. What can i do now?
