ExtraMarital Affair / Physical Abuse / Mental Harrassment

My Sister’s Issue: I have been married for 18 years with 2 children. My husband used to harass me for dowry, which my parents and family have been paying him whenever needed. Since 1 year he has been having an extra marital affair and has been physically and psychologically abusing me. He along with this sisters have hit me and badly injured me where I was bleeding day before yesterday. We live in a village in Telangana and we are hindus. The whole village supports him in his affair. When they hit me I tried to complain to police, they resorted to compromising and the whole village wasn’t allowing me to file a complaint, but next morning again their family started abusing me and he hit me again and said that he will get me into brothel case, fearing this and the pressure I attempted suicide. Wd d help of my brother, I have recorded his voice of speaking to his affair using an app in the last couple of days. My parents have filed a case, but we are not sure how to proceed further
