How to make husband to pay maintenance to his family

I am married (14yrs) and having two children. I am B.tech engineer. when my marriage got fix, I had to left my job. after marriage I started tuition classes but that also I had to give up due to suspicious nature of my husband. now as I am completely a non working woman he also don't give me money to spend on my own. I am totally dependent on his mood. every time when he fights with me, I always got in fear of, what if he refused to bring me vegetables or grocery ( however it never happened. he always brought the households and grocery) ) he also threatens me of giving divorce. But due to my situation of my kids studies, I am not able to take divorce. I want to know, is there any provision in law, abiding with which he had to pay me some money regularly for my expenses. as my daughter wants to take tutions , but he is not ready and I don't have money to pay fees. pls tell how I can get some pocket money while living with him without divorce. kindly help
