Can I get divorce from my bipolar husband?

Hi . I am a women of 33 years old. I married this man when I was 24. It was love marriage. Before marriage I didn't know he is a chain smoker and heavy consumer of alcohol. After engagement I came to know. But he convinced me he will quit once we get married. My parents were against it still I convinced them and finally got married. Then my bad days started. He didn't kept his promise of quitting bad habits. On top of that he started affairs with other women. When questioned he started physical and mental abuse. Both of us were working. But I paid for rent, groceries and for his b.ed and gave lots of money for his shares business. For 5 years it was only my effort to make this marriage work. After 5 years I come to know that he is bipolar and he had this condition in 2012. 2015 we got married. His father is schrezophenic. All this things I came to know after 5 years. That time only I wanted divorce but his mother convinced once he take treatment everything will be fine. Give one chance. So I gave one more try. But again it repeated because he stopped tablets and never quit alcohol. Finally I understood it's not worth so I applied for mutual. Didn't ask any alimony. He agreed first. But now he is not giving mutual divorce also and everyday harassing me. Now I am fighting contested divorce. Still I have not asked for any money because all I want is peace of mind. Can I get divorce as early as possible?
