Harassment by in-laws

Hello Sir I am an assistant professor working in a private Engineering College. I got married in 2008. My husband used to do practice in Jaipur High court but due to severe asthma problem he had to give up his profession. NOW he owns a petrol pump but as per his statement he is not getting any profit out of it. All the expenses of me and my 4 year old daughter are borne by me. My in laws have been harassing me since 2008. So many times they abused me as well as my parents. They never allowed my husband to have even a cup of tea with me. they forced me to cook separately in the same kitchen from which they never get out on time. i kept sitting hungry somtimes till 4 pm in evening. i am scared to pass though lobby and even to have water from the pitcher. My quilts are still lying on my bed because they refuse to keep them in the trunk. there are so many other things. My husband doesnt say anything rather he sided with them. They have many properties , quite well off. some of them they bought by selling off their ancestral land. tODAY MY FATHER IN LAW THREATENS ME THAT HE WILL THROW ME OUT OF THIS HOUSE THROUGH COURT. Once in the past i complained to the police by dialling 100 but i did not lodge an FIR because i did not want to break my family. I am suspecting that something fishy is going on in his mind. Though, i am not weak, i face them firmly. May be after provoking me they have recorded my voice. They never allowed my husband to even sit with me. i dont know why he is so scared. pl suggest what timely action should i take so that i and my daughter are not robbed of our rights.
