Mental cruelty by wife

I am facing marital issues as my wife left matrimonial home (1.5 years back) and living with her parents after pregnancy and moved to different state in india. I was subjected to mental cruelty by my wife and her parents with schemes plotting for my mental submission to them and to take control of me and make me surrender to them. wife is hihgly influenced by her parents and astrologers. I tried to talk to her and visited her multiple times alone and with relatives. All our efforts are wasted as she was not even ready to talk. i dont want to file rcr as they are pure criminals and i have proofs to support my claim. we have a girl kid. i would like to know how to proceed further. either notice or direct divorce case. They have never been transparent and honest with me. Always doing shady work behind everyone's back. How can i know whether she is ready for mutual divorce through legal ways as normal talking is not helpful. How the legal divorce case proceeds? what are our disadvantages? she is a working woman and well educated and earning good salary. they tried to frame me for dowry harassment. i would like to know what are the precautions to be taken for fake dowry harassment / domestic violence case? how to cover my grounds?
