Being mentally harassed by Wife and Father in Law

Hello, nI am residing in Bhubaneswar. Since over 14 months, my wife has been mentally harassing me. We have a boy of 3.5 years old. If I dont respond to her harassment, she makes the life of my child very difficult. Doesnt look after him and ignores him to get my attention to fulfill her demands. I have been happily paying for her education since marriage and she has been perusing PHD since marriage i.e. 4 and half years. She tells her parents that I am not providing her money or food or anything and have been ignoring her and says that my parents hit her and abuse her and all sorts of lies. My parents were government teachers and have never abused or hit anyone. During July 2022, my father in law entered our house completely drunk and abused my parents and myself the entire night. We have this recorded on camera for 4-5 hours. He also have hit me and my mother and my younger brother. He was drunk. He threatened to file dowry case and have everyone arrested. Kindly advise.
