Harassment me to my husband, mother law,brother law & all member

Hello Sir/Madam, I am married since Dec 2010 and have a baby boy who is one year old. I am a private sector employee and after one year i joint my office now. My mom in law, family and husband harass me every day for every single thing in the house, thereby making my life miserable. Actually my mom in law has major influence on my husband n he agrees to whatever wrong she says. Whenever he returns from office she creates one or the other scene and lies to him for petty issues. She tells lies to him and ignites fight/ arguments between both of us and clearly tells my husband, my husband also side in all family he say me enjoy ur life seprate dont disturb me & my baby its not ur baby you can also leave my life and my family, he is dont talk to me last two month only talk to shivya, maramari. I talk to him plz lets go and leave sperate room for us his not ready for that and most one thing sir his not saving any 1 paise his account, husband salary and also my salary hand to mother law. nahi diya to zagada karti hai. I m really very helpless as I hav got a small child to take care of. Also since my hubby is in a private job n earns less than me, he n my MIL always demand money from me. Though I always giv them the share from my salary still he asks me to transfer the entire amount to him. He doesn't even lets me know where he spends all the money I give him. I do not want to initiate the same however they are keen on it. my husband also threat me by saying that he will divorce I m really scared and under severe mental tension, as I am scare of losing my son. Plz suggest legal implications in this matter and oblige. in logo ko sabak sikhana hai muze plz sir kuch toaise batavo ki ye sab jagah pe aa jaye I will b very grateful to you. Thanks in advance....awaiting your legal advise....
