Yeah, it is emotional manipulation, even if your mom isn't doing it on purpose. It never ceases to amaze me how WT articles can turn things around so that the JW abstension from holidays is presented as "pressure" from "worldly" families.
Resist that "pressure"! Phone up those non-JW relatives AGAIN this year and explain how important it is that you NOT attend. What a fine Witness you will be! They will see from your "fine" example how morally superior it is to go skiing with your other JW friends than to sit around and have a pagan meal with your otherworldly relatives!
The same thing with parents of DF'd children. Somehow the society has convinced them that the fastest way to restore their children is to be FIRM.
Yeah right.
Through all that your mom is saying, I am hearing that she loves you and she wants the relationship restored. I like your love-bombing idea. I suggest you stop responding to the WT tape-recorder and speak directly to your mother's heart. When she begs you to return, say, "Yes, mom, I miss you too. Wouldn't it be lovely if we could sit together like we used to and.....". You can then follow up with, "If you want this so bad and I want this so bad, let's just do it!" If she responds with WT programming, just say "Sorry, mom, I won't, but I love you anyways." And so on.
