Domestic violence

Hi, I got married in October 2016. I am a working woman in a reputed Private Educational Institution. My husband is also working in a private sector in night-shifts.He himself came to me with marriage proposal.I accepted his proposal as he was my classmate during my schooling.Now we are 32 years old.At the time of marriage my in-laws asked for all the furniture and electronic goods to set up a separate family. As per their demand, my brother who is younger to me took all the responsibilities and all expenses towards my marriage. They did not demand for dowry that time but later on after marriage my husband started abusing my mother and brother daily asking for money.He never took any family responsibility after marriage. Due to his behavior I used to cry daily.After 3 months of my marriage I became ill due to Eosinophelia. Due to that I suffered for 2 months.That time also My husband and in-laws did not care for me.I was with my mother during that period.He always tries to take my salary and never gives his rupee to me even to run family.My in-laws always abuses me with vulgar language making my husband to fight with me.Externally they appear to be good but their internal behavior is completely opposite.I never tolerate the things which go wrong in-front of my eyes.Immediately I oppose wrong things. This has become one of the worst things in me to my in-laws and husband.Recently my husband and his parents abused my mother and next day they attacked my brother and his wife when they went to his home to talk about me.After attack my husband filed a case against my brother and his wife.One of his brothers is a police constable.He was also one of the persons who has beaten my brother.Now my husband included a statement that I have Asthma and T.B. Before my marriage I was very healthy.When I was ill due to Eosonophelia doctors told that she has no problem with her health she has problem in her family.I never had TB so far.Though my in-laws are abusing me vulgarly.They are not taking me home or allowing me to go to my husband.Mentally and physically they are torturing me. Now my husband is trying for divorce.He always refuses me going my mother's home which takes 30 minutes to go from my in-law's home.My husband suspects me that I give money to my mother and brother. From the second day of my marriage he is torturing me with his words and behavior.Can I file a case against my husband and in-laws?Please suggest me what I should do?
