I couldn't have said it any better than Scully:
So she's going back to your dad - the guy who insists on toeing the line to the WTS's edicts. The guy who is apparently NOT infallible. The guy who thinks so highly of his own self-righteous behaviour that he can treat you with contempt and utter disregard, yet demand mercy and forgiveness from your mother and the congregation.
Oh, yes, when caught, he did not want to be shut out from others, did he? And although he does want to toe the line with respect to shunning you, he apparently didn't see the need to toe the line with regard to the WTS stance on porn. (Ewwwwww) So,still, he prefers the appearance of righteousness in front of others in the congregation.
And mom wants to sneak around behind his back, pretending she has no contact with you at all. She wants to have her cake and eat it, too.
I feel sorry for mom. Things aren't going right for her. She obviously loves you very much, and is not really choosing not to have any contact with you, because she wants to e-mail you. But she can't buck dad, who doesn't want her to see you face to face.
I don't know what I'd do, except explain to mom how much her decision hurts you. Then of course, I'd cry because I would be hurt very deeply.
All they are willing to do to keep up appearances........
