Who hates Fay Weldon from She-Devil?

On the movie She-Devil, Fay had an affair with Roseanne husband. Roseanne took revenge after that. She left her children with her ex-husband and Fay. Fay treated the children like crap. She barked at the little boy for playing with the stick with the dogs. Her own mother even hated her. She live in the nursing home Roseanne worked at and she told her she hated the book her daughter wrote. Fay and Roseanne ex-husband are both fat and ugly, which is the insult they earned. Just because she isn't the beauty queen and her husband was a snob, doesn't mean she deserved to be cheated on.
