Stan -
I can so empathize with what you're going through right now. What is pathetic is witnesses cannot see the duplicity of their actions when it comes to shunning, kind of a 'don't call us, we'll call you' relationship. No one needs to be exploited like that, especially when children are involved. I feel like I'm about to go through the same with my mother, yet i'm not DF or DA and have only recently stopped attending.
My mother never calls or emails just to see how me or my kids are anymore, it's always are you coming to this meeting or this assembly? The only thing I feel like to my mother is a high pressure sale. It's irritating and off-putting to realize that someone is feigning interest in your life, just to sell you a religion. I 'm done being passive.
I think the best thing anyone, including myself, in this situation can do is to prepare yourself for it mentally and prepare for the worst. Kind of a reverse shunning. Not in a spiteful way, but enough to let a person know that their actions are thoughtless and hurtful, and you will not allow yourself or your family to be treated this way.
