She is not agreeing on divorce

I got married in feb 2019 and I am from middle class family. In my family only mother and my wife. Very next day to marriage she has started demanding some luxury items. She asked for apple i phone. Though it was not in my budget. So i gifted Red mi. She started mis use of this phone. Like recording conversation of my mother and sisters. And in our golden night she asked she will allow me touch when I will take her outside for honeymoon. Then me and my mother planned for vaishno devi treap. She said she will go only when my mother won't go. So we have dropped an idea. Later to complete her unnecessary demand she started threatening to us. Like she will commit suicide at our home. She started hating my mother. Neither she helped her and neither make her food and neither help her. One day on small argument she locked her self for 8 hours. We got afraid and we have broken the door and very next morning we called their parents and asked them she is repeating this second time. They not responded and we have asked something in written. They didn't provide any thing. She always try to frustate my mother and torture her in front of neighborhood and scold on her. She is 65 year old. She has made her life so miserable. And she always threaten us to call the police and arrest me and my mother. She neither agreed on divorce part and always create noise. Now it's been 2 month she at her parents home. How we can escape me and mother from her.
