My mother-in-law called me a bitch

Madi

So my mother-in-law called me a bitch and said I was only with my husband for his money. All because she demanded that he gives her $200 and I told her no. I know that's his mom but she has never helped him out with anything all she does is bitch at him. I've sat back and said nothing but I've had enough. What should I do...
