What do i do about my MIL?

She is jealous of you. You and your husband have to get far away from her and cut her out of your life until she learns that he is your husband now, and that's number one over him being her son. Those days are gone. My mom was like that. She destroyed my marriage. Destroyed. If your husband lets her walk all over you like that, maybe you should consider making a change where he is concerned, too. Your MIL is wrong. She needs to take her nose home and mind her own business. I am all the way on your side on this one.
