Its very general infact, mostly husbands doesnt tell anything to his mother, though she is wrong. The ultimate solution is not the one what you choose, left husband house. My suggestion is to be diplomatic, do favour to your mother in law in front of your husband, try to please her in front of him, never show him that you dnt like your mother in law, try to get his confidence in you so that he would bound to realise that somethibng is wrong with his mother only, once he will start telling to his mother problem will sorted out.
