Evil mother in law

Candy

So i honestly dont know what to do. Ever since we have been together my mother in law treats me like trash. There are alot of times my kids come home upset because she talks down about me to my kids. Like who does that??? We are a blended family i had two he had one we had two together. My husband wont ever stand up for me. I want to walk away but the problem is his daughter. We dont look at it like that. I cant leave her to my mils insanity.
