Verbal abuse from husband

Am a Hindu girl and my husband is a Muslim. We got married through special marriage act. My husbands family wanted me to stay with them and they don't like me going to visit my parents. My husbands is silent before them if any issues happen in his house. If he says something in front of them to support me then his in-laws will say he shouldn't be disrespectful to his parents. Since am coming from a different religion they want me to convert. Becauses of his parents and sister in law's verbal abuse i decided to stay with my husband who is working in another state. I don't visit my in-laws to avoid any ill treatment. Now I have a baby who is two years old. An finding it difficult to live because my husbands sisters make my life a hell by continuously asking my husband to stay with his parents. They are emotionally blackmailing him as a result of which there is continuous fights between me and my husband. Verbal and sometimes even physical abuse from my husband has become common. Am finding it very difficult to live such a life with my baby. Neither does my husband protect me from his in-laws verbal abuses nor he ready to live separately. What can I do
