I know very few people who have been successfully married where 1 spouse is a witness and the other is not. I know there are a few examples on this board.
A couple that I know IRL have split after nearly 25 years of marriage because of the stupid shunning shit. One of their 3 children got DF'd 6 months ago and that is when everything fell apart apparently. The father (unbeliever) banned the witnesses from the house because they started shunning his child. He never opposed his wife and was in fact very supportive. He let her raise the kids as witnesses but only 1 joined, the one that is now df'd. IMO he kept his head in the sand for a lot of years but had no choice but to see the light when his daughter got df'd.
From what my mom tells me she has moved out of the house and has filed for a legal separation because living with him is unbearable. Those were moms words. Congratulations Crooklyn for helping to break up another family.
