MARRIAGE DISTURBANCE WITH WIFE.

Dear Sir, I am into an unbearable situation. I got married in 27th Jan 2019 to govt employed wife (Postal Dept). She is pregnant now with 9 months . 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/cares me. And she also neglected my father & mother. In any small issue in my family she call her father/mother 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) 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 2 months. My family have tired to talk with her but her father don't allow for talk, he say i will think after delivery. And he say that, what will happen you wait and watch and we will see in court. After that issue she don't call me and also I don't call her. My questions are: 1. Her father threatening me we will see in court, if he do that what happened. 2. What will happened after delivery, he may raised false cases like dowry and domestic violence, how can i save myself 3. If she suicide in her house can i suffered / arrested. 4. After delivery can she is more legally strong for cases against me. 5. If she not come after delivery what can i do.
