Arrassment from my wife

Hi, Its been 15 years i am married. i have 2 sons( One is 12 years and the other is 7 years). Mine is a love marriage(Arya Samaj). Initially, My parents have not accepted me. we stayed outside. From that time, till today, we have changed 14 different houses and everywhere , its only because of my wife's filthy language. All this while, i was silent. Reason behind is . she might change. She is becoming more agressive and talks all the filthy language about my parents and will mentally harass me when i am at home or at office. Recently, she came to my parents house and harassing them to write their property to her sons. she is torturing them by sayng , she will do suicide in front of the house along with the 2 childrens. she is disturbing my brother's family also. she tooks all my salary every month. her mother encourages her to do all this. i am seriously in a bad state, not knowing what to do. My parents are afraid of self respect and my wife is torturing them again and again. Please guide me.. what i need to do in this case.
