How to get divorce if wife is not agree

I am 32 years old resident of Uttar Pradesh. I am an engineer and working in a private company in another state. Five years ago, I got married from the desire & emotional pressure of the family, which is very common in our area. After marriage we have never been interconnected and there is no mental and physical relationship between us till now. In the first few months of the beginning a lot of things happened so that I went mentally away. Meanwhile, there were many meetings between the people of our house but there was no solution. Now the girl is at my house and I have left home. Because of social constraints and rules, the both families are not doing anything and the time is being passed. It is not possible for me to come into this relationship and I do not want to continue this relation of the show, so I want to get rid of this relationship. For me, the whole time has stopped, I am getting away from my family and cannot do anything for anyone. If you have a solution,please suggest.
