Yes, other players mentioned this, and that's why I can believe that she falls for the guy at first, but as
psychedevil devil, she's intelligent and mature enough to resist once she rationalized that she wants her husband over the bad boy.
She said to herself and to his husband multiple times already that it's done with Christian, and she failed every time she tried to stop it. She's not even rejecting this new opportunity her husband is giving her now. So, why she will succeed this time? She will spend less and less time to bond emotionally with her husband (her work as a teacher plus now this new "work"), because, obviously, while the "work" with the boss remains, their sex life is dead. She already know that Christian is a total asshole, and she knows she loves her husband for the man he is, even if he's passive and not good in bed. So I don't what big revelation she can have with this.
