Want to live away from wife, she verbally abuses all the time, quarrel

I am undergoing extreme unhappiness in married life. I has been 6.5years, have two small kids. My wife keeps shouting, verbally abuses me all the time, zero understanding, very angry all the time. Gets frustrated and irritated very easily. She fights like hell, atleast once in a day. It breaks my heart badly. It is absolutely zero life for me with her and unbearable suffering. I am experiencing extreme mental agony and unhappiness. She won't go to her parents house because she has fights with them. I can't live with her anymore, she won't leave my house. I can't go anywhere, she will not leave me. Have very small kids. How do I proceed to separate from her?
