Just curious...did your Mom bring up the topic of "reinstatement then fading" coincidentally or does she know that was your intended plan at first? I can't imagine you'd have told her that was your plan
No, something got her talking about my cousin who got reinstated along with his wife about six months before I got disfellowshipped. They went to the meetings for awhile and then slowly stopped going. They live next door to us so she and my sister also noticed that my cousin and his wife started spending time with "worldy people" (the horror.)
Then she decided to that his intention must have been to go inactive the whole time and said that she didn't want me to do that, she does know that I'm having doubts about the Organization (among other things), but I haven't made a firm stand on it yet, I didn't want to do that until I had some other place to go in case I got kicked out, so I've kept the depth of my doubts and research to myself.
