She is young still even if as mature as she is. If she cannot be comfortable around them, she can set that boundary with her dad directly. But if she can manage to be okay for the time being around them knowing what she knows, then for now that is the best way for her. You have provided her with a lot of support and guidance. So she feels heard and supported.
Don, I disagree with you about calling people out on their bad behavior. Many times it looks like they are getting away with stuff when in reality, they are paying in other ways you can't always see. Sometimes, if people feel resistance or pressure in one place, they will just seek out support in other places...so calling them out really doesn't change their behaviors. It many times just displaces it. Boundaries work better because they are focused on protecting ourselves. You can't control what others will do...calling them out or not.
