Divorce against mantle and sexual harassment and cruelty

I was married in 2014, just after my marriage my wife started doing some misbehave life acting as she is suffering from some mental illness. Within a year she started beating me even once she made it on my mother also. After a while she got pregnant and delivered a still baby. After that she was desperate for having other issue and started doing sexual harassment to me. We didn’t have sexual relations since then. Suddenly she announced her pregnancy. I was shocked. How come one can be pregnant with sexual assault only while I was not involved. I went to doctor and filed a divorce petition under section 13. Since we were married she always forced me to start living separately. Due some family reason I never agreed. She do believe in some jadu-Tona thing too. On our first hearing she came to court after that she is continuously absent. Till date, we are staying in the same house, I have spent for the delivery and everything. She refused to leave my parents house and refused to divorce even. Daily she is fighting with me and my mother some time she crosses her limits to domestic violence even, I don’t hit her back but she is at her peak. Suggest me what to do I gave her divorce notice in her s cond trimester of pregnancy
