My husband is forcing me to get divorced.

I have been married since last 4 & half years. I was working in Delhi in an MNC before marriage but I left my job as I was getting married to a businessman in Varanasi. We agreed upon my joining his business immediately after marriage as I had done MBA from Delhi. He took a huge dowry amount along with several household things from my father during marriage. After marriage, he never took me to his office and kept on saying that I am looking for a good designation for you in my office. After 1 year, he took my jewelry worth 1 lakh as he needed some money and he never returned it to me. He started torturing me mentally, abusing me and hits me 4 times. He never wanted to have physical relations with me and whenever I asked questions regarding that, he got angry and questioned me why I am desperate for it. He told me several times that I don't like your body, it's disgusting and I'll never have a baby with you. Due to this, we rarely had physical relation. When my parents tried to talk to him, he refused about those incidents. I tried my best to save the marriage by tolerating all his ill treatments but he is forcing me for divorce since last 1 year. Now, he has filed a divorce with so many wrong allegations on me like "She is suffering from epilepsy due to which we never had physical relation", She left my home after 1 month of marriage", "She ill-treated my parents and hits them", "She hit me with shoes and fought with me and my family during her 1 month of stay with me", "She refused to cook food and do household chores just after marriage" etc. When I received his notice, I cried a lot and I begged him not to do this but he didn't agree. So, finally just to avoid all the mental stress of courts and cases as well as to teach him a lesson, I asked him for 30 lakhs for my future security and told him to file a divorce with mutual consent. He agreed on it and told me to go back to my parents house. He promised me that he will give that money exactly after 2 months and we will file a fresh divorce petition on that day but after 2 months, now he is refusing for any such commitment. Now, he is saying that he will give only 20 lakhs and that in installments in 5 years. Again, he is trying to ruin my another 5 years. What should I do now? How do I prove that those allegations are wrong?
