Cheating case against father in law and mother in law

I got married in 2009. It was arranged marriage. After and during marriage we found that my wife has chronic disease caller asthma. None of relatives and in laws side told me that she has this disease. As a result of this. She doesn't work much in house old. My mother at the aged 68 is still taking care. I too help my mother daily. My wife is highly unmatured in addition to that she has a very big violent behaviour. She has abused and told many bad words to my parents. She also threatened my father that she will dupe this family. About 3 times I happen to lift my hand on her due to her extreme high pitch rebellious argument. Recently in laws visited our house and threatened us that they will go to the police and also meet out neighbours and do character assassination. I do not have job from 6 years inbetween I have some job. Often she makes comments on my being jobless. And she critizes a lot. Because of her . House peace has gone. There is always argument. Her presence brings dis harmony. One day she left home early inthe morning and returned next day inthe after noon. One day she jumped our coumpond wall in the evening in some argument. Her wierd nature is a lot of concern .
