My family tortures me

Hello. I'm a 30 year old Hindu woman. I married a 27 year old Hindu guy when I was also 27. I'm a doctor and he is a businessman. We have a two year old son as well now. Before having the son, my life was all roses. My husband loved me and my in-laws adored me. It was an arranged marriage but it never felt like one. We wed almost a year later after we met, during which we met frequently and fell in love. However, after bearing the son, my life has turned upside down. His mother and father started torturing me on every little thing - be it a household chore, or my privacy. My husband, I realised, does not have opinions of his own. He blindly follows his mom and dad. If they would order him to sit, he sits. If they order him to slap himself, he slaps. Before the pregnancy, I could see a few of the absurdities in the house, but I tended to ignore it. I was focussing on being a good daughter-in-law and would do anything to win their hearts. But after the arrival of my son, I slowly started seeing a change in their behavior. They would expect me to do all chores even if I was unwell, they would check my mobile phone, they would not let me have my own personal locker to keep my personal stuff. They are a proper patriarchial less-educated family that does not understand the modern ways of life. I tried to be logical with them on all aspects but I would be talked down like I am just a maid at work in the house. They would never share any details of their lives with me. The things got out of control when I started standing up for myself and the father-in-law and my husband beat me and my leg broke. After that, there has been one more incident when the father in law has tried to slap me. Due to these two incidents, I was bound to share my feelings to the relatives and neighbourhood as a cry for help. But my in-laws started talking complete white lies in front of them about me. From the husbands of my husband's sisters, I came to know that they are sick people who do not get along with anybody and love their own family a lot and would not care if I left them or their own daughters came back from their own houses to live with them. Thus, they have started asking for a divorce. And now I feel like I was just a machine that was brought to bear them a son. Honestly, I feel the son doesn't have a brain of his own at all. I don't want divorce, which might come to you as a surprise. This is because I still have hope that if my husband lives with me separately, away from his mom and dad, I might have a chance at a happy married life. Otherwise, I can always go for a divorce myself too. So, I need your help in knowing if that is possible. Looking forward to a genuine help.
