Husband and In laws want Divorce. Can I apply for RCR?

I got married on 2018 and now I have three and half year old baby boy. Since I got married my husband was constantly brain washed by my In laws and for the past four years I am suffered with both mental and physical tourtures like making me away from my parents, friends & society and beaten without any valid reasons. Now they constantly tourture me to get divorce. I have special child and I don't want to give divorce. I cannot able to stay with my husband as the baby is suffering a lot in bad environment.He is not taking care of me and baby. Not providing proper food also.Everyday going through mental tensions.I cannot stay in my father home also. What can I legally do? My husband is having two houses. One in pondicherry another in chennai.He is currently living in pondicherry with his parents. n Is there any legal option available for me and my baby to stay in chennai house with some monthly maintenance? n Thanks in advance
