Marriage

Actually 3 years back I got married to a girl under immense family pressure. I was in love with someone else at that time and I expressed my parents that I want to marry a girl of different caste as we are higher caste Hindu they didn't agree at that time and they just fixed my wedding on my back at my home town at U.P. they called me to the home town and without realizing the fact that what would gonna happend and I reached there and then only I came to know that my family had fixed my marriage with some other person due to immense family and society's pressure they made me to marry a girl whom I never saw before. But after a very first day of the marriage I had an anxiety attack and got hospitalized the next of all this disaster. When I talked to the girl to whom i got forcefully married to, she also refused to have any kind of a relationship with me. I was so depressed and had no way to get out of that situation and return back to the city away from there. Now even after 3 years of that so called marriage we both have not consummated the marriage and now I want to get out of this status of being foolishly married. My marriage has never got legally registered ever I m living separately ever since then and now I want to move on. Please guide what should I do?
