What is beneficial

Since 2011 I'm married. Problems started after one month of marriage. Near about 4yrs I was in North East. My in laws used to visit there every 2 months and stayed there for another 2months. She always provoke against me and my husband is a mama's boy believes her blindly and starts quarreling with me without judging or knowing the truth. They started with my gold jewelry which I never gave on their hands. Her mother tried to prove that I am a loose character girl but never got successed. During all these incidents my husband never supported me. Now I stay in Kolkata and 6yrs after marriage I got pregnant and have a son of 5months. Still my husband is not at all concerned about us. All his properties are in his parents name., no bank account for me, no FDs. His mother has a negative thought about me that I will snatch her only son from them. But I never want that. Her mother wants all his money so still she is doing her job. During my pregnancy days she provoked all my neighbores against me, in my apartment. None of them talk to me. Presently I have in my mother's house. My husband not even ask about his son. Whenever my mother tells him anything he starts quarreling with her that all is my fault. I'm in a very unstable condition and unable to take any decision. As I want to give my child a bright future. Please suggest me what should be my next move. As my husband is only concerned about him and his parents. Vaccines of my son are too costly for him but his way of life style is never costly. Whenever I say to bring something for me he simply says he doesn't have any money but he can afford his life by doing parties with friends.. Costly dress for him.. Dining in 5star hotels. I have some voice records which are telephonic conversations between him and his mother which clearly proves that ahe provokes him against me. The greatest drawback in my husband is his shares each and every details with his mother even each and every conversations between me and my him. Plz help
