separation or divorce?

because of my mother in law's abusive language, interfering between me and my husband,dowry, irresponsibility towards my daughter, expensive nature and many other in toleratble habbits we had big fight and she thrown me out of her house at 10 in night. My husband took me to rented house after spending night in hotel. But from same night he started beating me and started fighting over almost everything.He changed over night. He didnt brought bed for three days from his house which was by the way only 100 -200 mtr away from our rented house. After a week he brought old and broken washing machine, broken fridge and oldest n broken bed from his house for my living. he use to left house at 8:30 sharpe in the morning and use to go to his mother. from there he use to go to work at 10-10:30 am. He used to get ready there only. he never brought his stuffs from his mom's house. He didnt even brought my n our daughter's clothes for 15 days. We use to be in two pairs of nightsuit only. He didnt let me order anything to eat like simple bread. he use to come home late at 9:30pm from his mom's house. after work he use to go his mom's place at 7:30 -8 pm. HE never use to take my calls during day time or he himself never called me even just to ask simple question "are u ok? you are alone there, do u need anything?" He started following to his mom's words blindly. on 16th Day when i observed his full behaviour for 15 days, I asked him "how our marriage is going to work?" to this he replied "see you can live here for a month, but after that you have to go back to my mom. and this is why I am not providing you with anything." After he left for work, i left that house with my daughter to my parents house. i called him twice to let him know,but he didnt bother to answer. Anyways I came back to my parent's. I have filed a complaint against my mother in law and my husband for dowry and domestic violence. I wanted to know my legal rights in separation. Also I dont want divorce but I cannot live with his family and he cannot live without his family. so separation is legal for how many years? what would be my financial support rights? and what if he promises to pay me particular amount every month and then after few months he backoffs, showing no income or anyother excuse? who will get daughter's custody? and if I get it what would be his or his family's rights on her?
