Need a divorce under christian marriage

Respected lawyers I got married in February 2010 In Delhi, my husband after a week of our wedding said that we might not be living together in the future, which shocked me. Upon asking, he gave lame reasons. He and his family used to mentally, emotionally torture me, so much so that i had to return to my parents' house for a fortnight. I made contact with him and went back to my matrimonial house (rented accomodation) but his behaviour with me became worse. He didnt want a baby but i got pregnant by him. Soon after this, his mental and emotional tortures increased, so much so that he was reluctant to even take me to a gynac. Then he started to scare me in several ways and even pushed me down a flight of stairs, eventually due to all this, i suffered a miscarriage. I returned to my parental house again for two months, upon a lot of insistence, he allowed me back into his house. But his behaviour did not change and finally after a life threatening action from him, i returned to my father's house, hoping he will change in time for better. All my attempts to reconcile on social level failed. He refused to take me back. Since july 2010 we are living seperate. I made contact with him 3-4 times but he refused. He even changed his office and residence; now his wherabouts are unknown. Last we spoke l, he said he will never give me a divorce. I don't want to live with this man, he is dangerous for me. I feel my life is destroyed. Please help me. I want to live again. Thanks for your time and advice.
