Harassment form father in law and sister in law, even my husband supports them.

I got married 2 years back. Its inter-caste love marriage. my in-laws was staying in Hyderabad and I was staying with husband in Bangalore. we has small disputes but in overall we lead a happy life. i got conceive and went to my mother's place at 8th month pregnancy for delivery. As soon i delivered baby girl, my father in law and sister in law started to brain wash my husband to leave me and from then for every small thing my husband started fighting with me, even stopped coming to see daughter. Once baby was 3 months, i went to Hyderabad to live with in- laws but they harassed me torched me badly. i suffered harassment from in laws for 2 months. After 2 months i went back to my mother's place, but mother convinced me to go back to Hyderabad. by this time husband got relocated to Hyderabad and he did not allow me to stay with him. He took all my things and sent me off. With no option i was living in my mother's place and looked after baby. Now my husband is demanding me to come to Hyderabad or else he will file case on my parents staying that " my parents are not sending his wife and daughter" I am really scared, why my husband show so much sadist nature. when i go to his place he kick me off and now he file a case saying that my parents are not sending me. Now i am really scared to go to my in -laws place. please give me legal guidance on how to fight and overcome this issue.
