To know about the law..

29y f, 2 children, 11 yrs of marriage. Married to a man 14 y elder n remarried to me, divorced first wife. He abused me mentally, physically, sexually for 7-8 yrs of starting, now he has settled down n stop abusing me. But m suffering depression n deep anxiety disorder due to the trauma. I really want to divorce him , dont want to live with him but m trapped bcuz of my children. He is very rich n inherits his ancestral property worth more than 200 crores rupees. I m stay at home, he doesnt even pay for my expenses too. I already pained a lot n m still in pain. Now m emotionaly very weak to decide to go which way. I dont know whether m able to face off the court issues or not, m deeply very scared. But if i do so, what is the responsibility will he be given by court to cater my needs? What is the amount of alimony i can get from him? My right in his property? I will definitely work for myself but until i get a job i dnt want to rely on my parents, n so i need money. Will it take so much time in court, m realy very scared??
