Wow. She sounds like a bitch, honestly. I really hate that type of racism. (Well, I mean all racism of course, but I always so infuriated when people talk that kind of rubbish.) I do feel for Bill though, separations are always hard and they've been together for a long time.
Although with what's going on in Troy's family right now, I think it's better for everyone that Cheryl and Bill have separated before having kids.
