Queries on dv and rcr

HI, I have been married since 8 years and i have 6 years old daughter. he is working in IT company and drawing very good salary around 3 lacs per month. And I am working in a public sector and my salary is very less which is rs 25000 p.m. I am facing physical, emotional, mental abuse right from the start. He has been beating me very badly even when i was six months pregnant. And now since 4 years he is asking me for divorce every two months on small small things like if I sometimes scolding on my daughter while getting her ready for school or If the rice is not cooked properly or even if the quantity of food cooked is slightly less or more. Now for around 2 months we are not staying together. He has left to his home town as his is WFH so he can work from anywhere. so since then i am alone managing entire home and my daughter and all the expencess as well. the residence where I am staying with my daughter is owned by him. he has sent me a notice through advocate for divorce two months back and i have also given reply to his notice saying that inspite of all his torture i am ready to stay with him so he should come back and stay with me but he is not willing to come back. So I have few questions as under 1. should i file RCR or DV case against him and under RCR can I get maintenance and residential right? 2. and what if i file DV and still he sells his flat then what action can i take against him? 3. How long is it going to take me to get maintenance under RCR and DV? 4. how much maintenance can I get as he is saying that he is going to quit his job from next month and wont be working anywhere then at least for an year? 5. As i am not having enough money to spend on flat maintence, daily expenses, my daughter's school fees what immediate action can be taken against him?
