Divorce

I have been married since 2008.there was alot of issues within the marriage.i was married at 17 only. Although they my husband and in-laws helped me financially to complete my dentistry but my husband's and mine relationship was not working due to his nature and behaviour. He used to drink alot several times he have given me pills to abort our kids as he was not ready and given excuse that I was too young but even after my college his behavior stayed same. I left my dental job just to help him in his new startup but then my in laws started treating me badly. Since 4-5 years I m staying with my parents. Earlier he dint used to send anything for my survival but now he has started. But he is torturing me in other way now he has convinced my parents just saying that reputation will be at stake if I leave him. But I want now to leave him as while I was with him then also he tortured me now I m seperate then also he is doing same. He is raising fingers on my character and everything mY parents are supporting him. They all have beaten me many times just because of them I m not able to work any where. Please help me what should I do. What legally I can do.As Now it's threat on my life as all of them have became animals.
