Related to Annulment of marriage

Respected all, I was 18 year old when i was married , i was born on 5 August 1998 , my wife was 17 years old and was born on 7 august 1999 . We married on 11 February 2016 . At present i am not able to continue this marriage.After my marriage i left my home for further studies and i resides in other city , till date i went to my home occasionally. After one and half year of our marriage passes my wife started living in my house at my hometown i only went there occasionally.We both are underaged during our marriage, we mutually talked but she is not ready to give me divorce or to live alone . If i forcefully break the relationship she will attack me with cases of domestic violence and false dowry case. She often threatens me that she will commit sucide or any may harm his body . She says me that she has married forcefully , her ex boyfriend cheated her and she marries only for the happiness of her family, i cannot further compromise with her from past one year i am compromising all things, but now i decided to leave her . Can annulment can be filed in the court on these grounds, i had proof of my age, i hadd certificate of marriage issued by local marriage committee (Samuhik vivah samiti) , I only has one fear that if she attack me by false dowry case or domestic violence case or by committing sucide or may harm her body my whole family will pushed behind the bars. So i decided to take opinions from you,
