What to do

Hi, I have a 4 year old daughter. there was a lot of domestic violence involved in this relation. Domestic violence started 3 4 days immediately after the marriage when we in delhi.(we both are from Mumbai, since his temp posting was in delhi i moved to delhi post marriage. we stayed in hotel for 6 months approx) My husband is a software engineer by profession and i was into media. every 3 months he used to hit me till i could bleed n swell. Hiting was such that i couldn't even eat. he also tried to strangulate me once in delhi. I am assuming that he was very very short tempered person. I tried to leave him multiple times but i always got convinced and went back to him.I never filed any police complaint against him.Though I come from very strong legal family background. Off late the domestic violence was reduced however there was a lot of torture happening on daily basis. During this lockdown i finally left him as i could not take the torture & even domestic violence. now that i have come to my parents place, he tried his tried to convenience me to come back but i did not go. I stuck to my decision as my daughter was getting mentally hampered looking at the fights daily. It mentally affected her badly. As i wasn't going back he got even more frustrated. I hardly used to call him. But he kept calling me in intervals and tortured me over the phone I really did not understand what to do. I was always of the opinion to keep my family away as much possible. He did take money from my parents which he returned. at times i also felt that he had some phsycotic issues however wasn't sure. But in this 5 years of my marriage i went under depression and i started psychiatric treatments. Because I wanted to be normal for my child. Now my husband is so frustrated with me that claims that i only tortured him for 5 years. He is been sending all chats n communications and fotos whatever is possible to his teachers, friends, family etc i dont know the reason why. According to him everyone is asking him to stay away from me. He has always been abusive towards me n my entire family. He took the daughter for 3 days during lockdown. I thought he must be missing her. He took the daughter to his parents he said he will get her back very same day which was Friday, he kept her on fri sat n sunday he brought her back. Sunday morning he called me saying he will get the daughter back today n then he stopped answering my calls. I called him for 6 hrs at 10 pm he called back n said i fwas sleeping.and he started claiming that because i called him so many times for daughter that has creayed problems at his house. Ofcourse beacuse i had allowed the daughter evn i had issues at my house too but i never uttered a word about it. I havent given him divorce yet. He is saying he will file for divorce in 2021. My parents have adviced me let him file for it first. I am actually unable to undertsand what to do. should i go and file divorce or wait. please help...
