What should I do if my dad doesn't want to take care of me and my sibl

I'm 21 Female My mother died on 26th dec ,2023. We are 3 sisters and 1 little brother. my father is being abusive towards us . And he was trying to fool me by saying that mother's soul has entered in my body to give him sexual pleasure. He was directly asking for sexual pleasure from me. He drinks every day. When my mother was alive, domestic violence was everyday story for us. She died due to heart attack. Now my father is trying to get marry again. I don't think after marriage he will fulfill our study expenses. Recently he bought a car but after asking for 5000 for us siblings daily needs. He said he has no money; he will not give any money and will not buy the product too. He said to go ask your mausi for money. So is there any solution to this problem? I mean if gets married again. Can money needed for our maintenance, such as school fees etc. can be paid directly from his bank account and I don't have to beg for it from him again and again.
