Mental torture by husband and in-laws

I am married for 4 months now. I am a software engineer and my husband is earning less than me. He and his family were good initially till our marriage happened and till 3 months. I come from a middle class family and I am giving a part of my earnings to my parents. They were all okay with all this and married saying that they don't want anything in terms of dowry or my salary after marriage. But all of a sudden in the last month just for a silly reason of fight over food they have started abusing me and my parents by saying that your family is torturing you for money and my husband is humiliating my parents regarding their financial conditions. Also husband and in-laws are abusing me saying that I am mentally unstable and I am trying to separate them with their son and I am torturing them mentally. They are trying to bring me down emotionally and mentally because of which I am unable to carry out with my professional career on a daily basis. So for time being I am staying with my parents. My husband is also listening to his parents and abusing me. Please suggest how to go ahead with this.
