Husband wants divorce due to mental torture by wife but she doesnt..

Hi, I have been married about a year and some months ago. Initially things were fine, but slowly my wife used to fight with me because out thinking and lifestyle was very different and there was no understanding between us. Gradually my wife have started doubting & blaming on me about my extra-marital affairs. she always tried to humiliated me, my parents and our reputation in society. After about 10 months of our marriage, she behaved very rudely with my parents due to which i had to leave the house with my wife and shift at a different location away from my ailing parents just to keep her happy, as she was not able to adjust with my parents. During this time also, she forced me to not go to meet them neither bear their livelyhood expenses. A month ago, she called me and told me to push off my parents from their own house and told me that we shall shift to permanent house and push your parents off to a rented house because i was paying the EMIs of the house, to which I denied. She on hearing this denial threatened me that she will throw my parents out of the house and get them pushed off on the streets. Ever since then i have filed a NC against her and have asked her parents to take her back home. She also doubts that i m in an affair with another lady due to which i m planning for a divorce(which is not true). Also during the fights in the last one year she has mentioned that she wants divorce from me, but no that i am going to file it, she refused for the same and she asked me to take her back at my home. She said she doesn't want alimony or doesn't want to file a case to court; but she will also not give divorce to me ever at any condition and said she will not let me go ahead in my life as her revenge. How can I get DIVORCE from my wife?? (NOTE: We haven't registered our marriage) Please help me the best way through this. I am not willing to pay her any alimony as she is quite capable of earning for herself(She had mentioned that she holded a decent package before getting married to me). Thanks.
