Domestic violence and mental torture of mother in law and sister in law

I do a govt job and my husband is an unemployed.we are married on 9/10/19.My sister in law remarried with her first husband's brother without any legal divorce, with full support and consent of my mother in-law.In my matrimonial family our grandfather is alive and my father in law and grand mother committed suicide few years ago in different time for the abusive language of my mother in law and no police investigation had done. 6 years ago my sister in law remarried and from that time she with her second husband and children live in my matrimonial house . The house and other lands are in the name of my husband's grandfather (90 years old)who get pension and all pension money take my mother in-law and sister in law. Within 2 days of my marriage, my mother in law and sister in law told me that I have to live in rented house or have to buy flat or land bcz , I can not adjust in village. First time , I , just take it lightly and told them as I do a govt job and my posting place is 100 km away from their home, it is really not possible for me to live in my husband's home regularly but during the time of occasions and festival and holiday time I must come my husband's home for living with them. After that when I come their home my mother in law and sister in law misbehaved with me and did not give me to cook food or offered me any food and again told me very rudely that I should buy my own home for me and my husband. My mother in law snatched our bed( which was gift to my husband from his grandfather) and expensive woolen dress of my husband from my almirah( which was gift from my father) for her daughter and son in-law. I told them many time to return my bed( divan) and cloths but they never back my things। June,2020 they forced me to leave my husband's home and now I live in my father's house with my husband.in June , I lived in my husband's home only for 5days . On that time I was 3 month pregnant, when I revealed this news to my mother in law , her behaviour become more worse and one day evening I saw 15 to 20 villagers were coming in our home . Suddenly they asked me why we hurt physically my mother in law? And this was totally surprising for us! Now I am eight months pregnant and I told my mother in law that I will go there after my delivery as I will get 6 months maternity leave. Then she and her daughter deny it. And blackmail my husband that if I go there for living, they will not give food to our 90 years old grand father.As I do job it is not possible for me to look after him permanently. So my husband is helpless. Can I get any legal help?
