Can I file for divorce on the ground of domestic violence happened 7 months back?

I am in a mentally abusive married relationship for last 12 years, my husband raised his hand on me on 26th July, 2020. I did not go to file for FIR, as I was not in a condition to go anywhere else. And then he left home and remained at his sister's place for 5 months. He touches me inappropriately without my permission which I don't like and he says I don't need your permission. I have discussed these things with my sister-in-law over Whatsapp chat, and he read all those chats. I have discussed these issues with my elder brother over chats and he has advised me to get a job and become stable first then go for separation. I don't have a job right now. Now he is threatening me to disclose those chats in Court. Can these chats be considered as evidence? My husband is acting crazy over those chats. He does not give me money for household expenses. Every time I have to ask him for money. We are living in his sister's home for free for last ten years and his Jeeja is a very rich and influential person, he has tried to molest me as well. His jeeja is given very much importance in my family. I told my husband about this incident but he refused to believe. Every time he makes vulgar remarks over video call. Please suggest to me how to get rid of this relationship as it is affecting my mental health. My son is getting affected and I want to keep him away from these things. Please help me, I don't have money.
