Torture by mother in law

Hello Sir/Madam, I am married since October 2015 My mom in law 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 and my husband never say her anything if he says anything then his mom start vulgar words . Whenever he returns from office she creates one or the other scene and lies to him for petty issues. I m really very helpless , as even I have heard saying my mother in law tat she wants to make my life hell and if I do job I have handle her my whole salary and then I have to ask for penny before use and give her description where I want to use money Please suggest what should I do file a case for divorce. I m really scared and under severe mental tension, Plz suggest legal implications in this matter and oblige. I will b very grateful to you. Thanks in advance....awaiting your legal advise.... even she is getting housing benefits and government pension.
