Want divorce, mental harassment by husband

My husband family pressurized on my family for my marriage with him who is my relative, I didn't wanted to get marry with him but my family members made me emotional & taken me directly to marriage hall & I was stunned & not able to do anything at that time & my marriage done. I was not knowing they have planned for my marriage before 2 months distributed visiting cards but warned everybody to don't tell me that thay have fixed my marriage. Before 3 months of marriage they have done my engagement with him in small room where I was gone for relatives marriage ceremony, they have done something like black magic or hypnotized me that I didn't remember what happened on that day with me I just remember I was tired that day & I slept in bus while returning from relatives marriage I don't even remember how I came to that bus. I was in a depression for around 6 months & not able to think anything after marriage. I don't like him at all he is psycho, he do only wrong things, he fights with me in public shout on me, harrass me, taken loan on my name, we are not mentally & physically attached to each other I hate him completely. My family also don't support me I told him I want to leave him but they always try to convince me saying it's u r destiny you have to be with him, I told my husband I don't like you & give me divorce but he is saying I don't give you divorce if you are not happy then it's your problem. I am from Tamil Nadar community was living in Dharavi Mumbai. I am Christian & he is Hindu I doesn't wanted to get marry with Hindu because I wanted to stay in Christian community only. He is not matured enough to understand the meaning of marriage, in marriage we can't force each other to be with someone without their will but I am living with him without my will. I will go for suicide if he will continue harrrassing me mentally. Please advice me how I will get divorce if I am not happy with him & he is not going to give me divorce.
