I agree you have to stand up for yourself. My dad always badmouthed me to everyone. And then his wife starts badmouthing me and my husband. So I let her have it and told her what everyone thinks but is too polite to say: that she's a gold digger and a B*** my dad demanded I apologize to her. I didn't, and didn't speak to them for almost 2 months. Then my dad calls not wanting to fight because he's on his last legs. No one apologized to anyone, but it's more like a truce until he dies....
