Can Physical and Mental abuse to MIL by wife help to get divorce

Just to share few aspects here I have been married for close to 3 years now and in these years my wife has hardly spent 3 months with me in my house, every time she is here she creates issues for small things and goes back to her father place. And during her stay here she treats my mother very badly. Initially she use scold and utter all sort of bad words to my mother when I was not around and few times in front of me to she has done same. And even with me she behaves same and she has talked all nonsense to me as well. This has gone over my limits now. Recently I have installed hidden camera in leaving room and this time she has passed all limits. She not only utter bad curses and filthy physically abused my mother by trying to through her out of the house, hit her couple of times, try to suffocate her by apply force, call her characterless.. Etc. All this got recorded in hidden camera also I have several phone conversations recorded where she is abusing me, my mother and my family. Even her parents support her and say she is like this and we need to adjust for all these. She also threatens me of suicide if I don't go by her, all she and her parents want is I should stay separate from mother to which I have clearly said no. My mother is above 60 and she is alone I am the only son and my father is no more with us. Can these evidence be of any use to me to prove me and mother not guilty of anything, I am sure now she and family is planning to lodge false complaints on us. I can't take this relationship anymore and want to come out of it. What would be best way to come out of this hell.
