Any legal ways

I am living in bangalore. I got married in 2007. I finished my BTech ( Information technology) I have two kids both born in abroad. After he completed his PhD we came back. After we got married he went abroad and I went after 60 days, bcz if visa...... From the next day of my marriage my mil started telling all wrongly abt my family. She wants to create a bad image of us, so that her son will not leave her. They got and getting all financial support from him, including his sister. After returning from abroad ( completing his PhD, I helped him in his project for software area) he wanted to apply for.loan to construct house in home town. I asked y to get loan. U were earning much in abroad, and we got 10 lakhs for my first kid from that country. From that day onwards big quarrel and beatings from my husband started. I was patient when I was out of the country( since my passport and kids passport are always with him) But when I came to india I started asking everything. So the entire family started torturing me. As of now he is torturing me telling that I should not own a two wheeler, I should not do any course, I should not speak with neighbours, and finally should not go for a job....I should not do any work independently. Two days back he was telling I roam after kids go to school( which is not true). I told if u think so, let me go to job, and this problem will b solved. For that he hit me like anything with kids cricket bat. I got hurt much. My parents family ard telling leave that psycho And come, we will take care of ur kids. But I want to know is it possible to warn him, by some persons so that he gets afraid to beat. Or is it possible to go to my hometown and get any expenses from him for kids studies and myself. Bcz nothing is wrong in my side. One son completed class 2 and other son completed UKG. He broke three of my ear rings and my ear was torn, each time he hit me. I feel very depressed, since he controls me more and we r living in such a small house which is not at all enough for family with two kids. Since my parents side r good enough to afford me financially , he will not allow me to get anything from them, and he also does not buy. But they come in between when he out of station and buy all things needed for us. I don't know how to deal the situation. Plz help me.....
