Unhappy married life

My wife does not support me to lead a normal happy life and always argue with bad words for each and everything in day to day life. For those kind of situation initially i take it as her usual behavior and certain times it crosses the limit of her language she use to me and my family (My family - my Mom, Brothers, Sisters and their families and none of them are living with us though). I am not able to express each situation i am going thru. If i get any lawyers advise, i can surely explain the situations) Just to give my background, we have been married since 6 years and it is my second marriage and my wife's also second marriage with a daughter she was having from her ex husband. We have blessed with another child baby boy 2.5 year ago. I am keep on expecting a normal happy peaceful day to day life without any hassle. These days it has become too much specially after having our second child (1st child biologically for me) and she started targeting me and my family members. In her family she is the only child and financially well positioned. That is causing her intention of get rid of this family stuff and she is trying to settle in her parents house along with my child which i am not at all ok. So for each and every things in day to day life she brings up the issues and directly start talking to divorce step. Every day its a same story. Please advise
