My husband is not responsible towards me and my kids?

My husband is listening to his mother's words and always torture me mentally through words. These words make me anger and if I start answering him he starts fighting with me and his parents enter, and blame me. My husband's mother expired at his younger age and his father married other women, she bought up y husband and his sister. Now, for that reason she says from first day of our marriage I'm taking away my husband from her. Because of her I got abortion in the 8th month and from the time I conceived till abortion they did not allow my parents to visit me or talk with them. After that I gave birth to two kids both are girls at that time my father-in-law abused my mother as my younger kid suffered with jaundice for 20 days after she born. Even then I did not say my in-laws any time a word. Once when I was at mother's place, they asked me to stay for 20 days and at that time they took my husband for surgery, and they told me at last moment when he was being taken into operation theatre. I love my husband very much but he his encouraging his parents to tell bad about me for relatives and neighbours instead of stopping. Two months back he beat me very badly, so I came to my mother house and staying. I tried to approach him by calling but not lifting my phone, but talking with my uncle and saying I'm denying his parents. I never denied them but asked not interfere in our personal life. I need a suggestion regarding divorce? How to apply for it and I'm jobless at present will I get any compensation? Previously when I worked I gave all my salary to in-laws, will I get that money back?
