That's another thing. Brenda knew that her daughter was being sexually assaulted. So far as we know, Anna knows that Josh watched CSA, and there's no evidence of anything else.
So Brenda ignored her 9-year's statement that she was being raped. Anna is ignoring the feds statement that her husband watched CSA.
Brenda's denial is far worse than Anna's, imo. But Anna is thought to be foolish for remaining with her husband.
Even the post title ("Oh, honey, it's . . . ") implies that the situation is so terrible that divorce is the best option. If watching CSA is a reason to go (and it certainly is!), then a little girl being assaulted should also be one.
Both women had the same serious issues (lack of money, skills, childcare) that made leaving very difficult. I'm not sure why they should be held to a different standard.
Most of all, though, I feel sorry for Jessica Willis. It must be hard to be close to her mother. If the police hadn't become involved (thanks to Jessica), Toby would be assaulting the youngest Willis girls right now. Brenda showed no signs of doing anything to protect them.
