Mental harassment by wife and her family members

I am Amit Sharma. My wife gives mental tension to me and my family members. She is cynical and has tried 2 times to cut her wrist and when we informed her family member’s threat us that we tried to do this thing. As per them, we scold her do mental harassment, which is totally wrong. As per my wife and her family, I can be love affairs in my office as she knows that there are some beautiful girls. Which is totally wrong because I have advised her that she can ask anyone in my office for my behaviour for the same. She and her family always create some drama in my home and they always scold on She and her family always create some drama at my home and they always scold on me and my parents. In simple words, I want to break this marriage and want a mutual divorce with her and we can not pay any alumni payment to her. We don't have any child. My married life is being 1.5 years only. We are from the Hindu community.
