Divorce and alimony

Hi, I am married for 11 years, don't have a child. My husband is not interested in planning a family. He and his 2 sisters are all after property. My in laws were living with my younger sister in law, as their plan to get the property. My mother in law expired last year, now my father in law is still living in my sister in law's house. My husband and his sisters are all after money. My husband doesn't give me any money, takes money from me if I get anything on Rakhi / occasionally etc.. He abuses me mentally by saying nobody likes me, his relatives hate me, you cant give birth to a child, while he is having problems. He has taken all my gold and never returned. I am thinking to get separated , but he doesn't want to as he thinks I am doing his tasks all by free like a maid but there is no happiness and attachment in this marriage. I want to ask how much money can I get from him legally. How can I do that? He is greedy person, all 3 siblings fight over property, so don't think he will give me anything.. he doesn't even him me any money.
