After 10 years of marriage, my wife tortures me mentally. I have 2 kids

I married before 11 years and my marriage has been troublesome since then. My wife refused for going to honeymoon. She ran to her parents house after one year of marriage putting false allegations on me of physical abuse, but, started calling me for coming back after 3 months. I brought her back. She and her parents used to putting false allegations on me and my family to my relatives. She was living comfortably here and used to portray opposite image. For this me and my family visited their parents many times to clarify things and asked her parents to let her get accommodated in her new family. This continued for many years, after 7 years of marriage she went to her parents and did not come back, on putting pressure for children school and education, she said their admission is done at her maternal place and I need not bother. After 3 months when my grand father passed, she came back with kids and her father and stayed. When I talked to her about incident, she said sorry and promised to not repeat and live peacefully. After 3-4 months she went to her parents place, when I went to bring her back, she refused to come and sent children with me and stayed there saying that "I will come after 2-3 days". She stayed there for almost 1.5 years. After 1.5 years (after multiple social meetings) she came with her relatives and parents and all felt sorry for her behavior, her mother promised to not interfere in our life and she again came back in my life. After sometime she started misbehaving and abusing. This abuse continued and grew stronger and more frequent with time. My parents were very tensed and they asked us to leave their house and live separately somewhere else. My wife refused to move out of house and started targeting my parents using abusing words and language. We got temporary partition in our house and built a separate well furnished kitchen for us. Now my wife got more angry and started fighting with me for non relevant issues and torturing me mentally. Even calling my parents name and using very abusive language and even slang for me and my parents. I have come to destroy you and your family, "barbaad kar dungi", I will murder you, jaan se maar dungi. and putting false allegations on me of beating her. She used to beat children which grew more after separation. Now, after trying my level best to save marriage and for sake of children, I have given up and moved to guest room in my parents portion. Now we are living in same house, I with my parents and she in separate portion and I am managing all her needs (grocery, milk etc.) I have 2 kids(10 yrs daughter, 7 yrs son) Please suggest what should I do.
