Slut In Law Mother In Law See's Me "half Naked", Then Calls Me Fat And A Slut..?

Mother in law see's me "half naked", then calls me fat and a slut..? - slut in law

My mother spent a week with us (last week without prior notice univited came) ... And yesterday evening he was here, went to my room and my husband during sleep and light again. I woke up and saw that they disgust me and said she thought it was in the bathroom (I doubt that ..) My husband has one leg over me and I've had in my stomach and he wore a T - Shirt and clothing inside, that's exactly what I sleep in. .. Then the next day he called his two daughters to tell them that I'm fat, I'm not a prostitute, and recognized how much I everything to his son (my husband) .. have left and also asked his niece and her boyfriend of her niece, say the same thing. How can I do? I did not ask my husbandsay anything until I had time to think .. because the child is somehow still seems big to a person reacts to something stupid needs. I mean, I was in bed with my husband! I was (completely naked and I may be) if I wanted to, and not all walk. The lady looked at me in my underwear, then overreacted!
How can I do? Should I leave them alone?
