Mental harassment of me and spouse

Hi All, I am married since 3 years. We stay in Pune. We have a baby who is 1 year old now. I got married following all the orders and choice of my parents. Post marriage we got a lot of issues at home. My sister delivered a baby just after our wedding. For helping my mother, my wife stayed at my place for 3 months. During this time, my mother raised a lot of complaints about my wife. All those were listened and ignored by me initially. On the other hand, my wife was also telling me such things every day. Somewhere after 1 1/2 years, when I alone went home for Rakhi, my sister, mother and father fought with me on all those issues. I took my wife's stand because I felt that she is less guilty and there was a turning point in our life. After that incidence, all of them boycotted me and my wife. They didn't even ask us when my wife was pregnant. When we got our baby, they came to see him in hospital. But did not come to his naming ceremony as it was in my wife's place. Everything went so wrong that we given up calling and talking to each other. When it was my sons first birthday, I called my father and my sister's husband to come to Pune for Birthday. None of them came. Now my sister went to my home and she told my parents that because of me and my wife, she is having problems at their home and with her husband, whereas there is no such thing (as confirmed with her husband). Now my father and mother are getting furious and fighting with us. We are equally not in a position to listen them as we know it is totally wrong. The situation is largely out of control. Please suggest me what should I do now?
