I want divorce but husband is not ready to give

From the date of marriage from 2014 he don't support me in any way neither financial nor moral. Then initial days itself he started torturing me for money, beating me and even taking out thaali. I was working as Assistant professor at vellore during that time I even supported for his lease house at bangalore by providing 3 lakhs money. Later I got pregnant after 8 months but even then he didn't change after that. During those days of pregnancy in order to upgrade my qualification and support my kid I joined PhD at IIT. He and his family members fought and didn't allowed me to pursue it since they were afraid that I may dominate over him since he is B.Com. Later I somehow manged to come with support of my family members and relatives. Then successfully I delivered to a girl baby and now doing my research perfectly good. I gave him four and half years time I adjusted he didn't bother of me and my kid. He didn't take any responsibility towards me and my kid. I am supporting myself and my kid liabilities solely with my stipend. I adjusted for everything I took all things on myself never forced him for anything even though his torture continued through physical and verbal abuse. Finally I have decided to divorce him since I am not able to take up any more and there no use of doing so. I filed a case in the family court I strongly don't want to stay with him and he is also not ready for mutual divorce. What should I do now Can you please tell how long it take for contest divorce. I have all proves supporting on me giving him money and he hasn't taken any responsibility for us.
