I get where the trust issues come in. If everybody in her inner circle is a cheater and cover for each other. At some point you ask yourself or they covering up for her. Or at least trying to get her to do what they do. Afterall, I doubt they would be too comfortable with her having all this dirt on them and could spill the beans at any point without them having anything on her. But if she hasn't given you a reason to worry, then try to avoid having that discussion with her.
