Divorce

I got married in 6th June 2015. Having a kid 14 month old. My husband is having an affair and do mentally physically abused a lot. From starting days he started abused but due to family pressure I ignored everything. But now its high time. He is happy with other girl from past 2 years. I am suffering from mental abuse a lot. I have a whatsapp chats of both of them. I left that house on 4th april 2020 in period of lockdown because they are pressuring and torched next level. My husband Slapped multiple times in that period so i orefer to step out. I am at my mother’s home this time. My baby is with them only. Now, My-inlaws dont want me to come back. Truly, I want to continue but He is having an affair and I don't think there is a bond left between us. He abused me and my parents like anything. So what should I do? That’s why I looking for an advise. They want mutual divorce so Can I ask for compensation from them? If yes, how much? Its been 2 months now. Can I file custody of my baby with maintenance without divorce? Or should I wait for them to file a divorce because they aggressively looking for divorce? My mother-in-law said that I wont get anything because all property is name of her not on My husband’s name.
