Wife Left home and is Physically Violent, what action to take?

Hi, I got married before 5 years and don't have a kid. My wife is short tempered and become abusive and violent on very small things. Before one year she asked me to leave my parents and i did. but still the same condition. Her family members also starts abusing if i tell them about her behavior. She starts breaking the things, abuse , hits me and threat me for suicide if her wish was not fulfilled. Last week she did the same and after asking the reason she said i frustrate her. I told her that there is no definition of frustration and for this you can't abuse or hit me . But she left home and staying in PG. Me too left home. Yesterday i came back and saw that she came in between to take her daily need items. What should i do.
