No one changes unless they want to. This guy has no incentive to. He isn't getting a show back and his wife isn't going anywhere. He really doesn't even need to go to rehab unless this guy does some sort of talking circuit in the religious world, or something, and he is trying to salvage some rep in that world. Other than his show, the only thing this guy will lose is the email he used for Ashley Madison(and by that I mean he will get a prepaid credit card and a new email that doesn't lead directly to him).
