Its been 2months of my marriage n really im having a very bad time with my mother in law.?

She is not at all clean and hygine(she even doent clean her hands after coming from bathroom) and even she doesnt keeps home clean too.after marriage wen i came home we cleaned everyhting and said her to take rest and we will take responsibilty of cooking.for she started shouting and complainng the things to neighbours in the apartment.Even my husband know everything aboutt her. wen we both r out of home she comes and searches everything and sometimes she takes money from her son's pocket with out asking.all the time she observes me. But for the world she is very innocent.nobody knows about her cunningness coz she manipulates the things and behaves very innocently.. and all her relatives left her due to her head strong mentality.its been only 2 months of our marriage and my husband is the only son.Give me some idea what to do now....
