Husband, mother in law and sister in law with three kids harass me at home.

My husband for the last one year abstain from physical intimacy. 24 hours he is in service of mother and sister. Mother in law and sister in law harass me verbally by abusive language and make me do all house hold chores. Prior to marriage it said she lives separately and you will live in first floor of the house. Now they have bought me down and dumped me in one room along with my 3 month old son and are saying what is the need of privacy. Mother in law says she asked his son to sleep with me for those two days so in society if someone says why they are doing it all they can say ki how the child is born if sleeps somewhere else. One man daily comes to house and sits with mother in law and husband till 11 o clk in night. I asked for a separate kitchen they are not allowing me that also. My life is shattering into pieces as these people are hiding even things of daily basic needs too. I am unable to understand what I can do to live with my husband peacefully as he is totally in his mothers hands. They say we will take the child from court. Sister in law says Leave your wife as I have kicked my husband
