Got married but not stayed together since day 1 after marriage

My parents forced/ emotionally blackmailed me to get married. And after marriage he and me never stayed together. He works in some other city and I work in Hyderabad. I stays in private hostel. We never met physically. Its been 1 year now. I'm begging my parents and him to divorce me. But they are pressuring me to sleep with him. And i already told everyone either give me divorce or rather I go for suicide. But no thought of staying with him. I'm feeling helpless. How can i get divorce and can i file a case against him or my parents?
