Understand what you are going through as I am suffering the same. It's all going to depend on how important fading out is to you and how much you guys can actually handle when it comes to "pretending."
I am to the point where it has become increasingly hard to lead anyone on that I am still going to the hall (we did the switch to new congregation bit) simply because as more time passes- the stronger I have become outside of this sick cult. Yes, sick CULT.
Avoidance becomes almost impossible- so you have to be strong in the conversation. Dominate it with POSITIVES on your life and the world around us. Talk about the amazing things science has done or something they cannot argue. Use logic and just steer the conversation around every nosey question.
Keep researching during your fade and stay strong. Hope it all goes well! You are not alone thats for sure!!!
