At the risk of repeating myself, shunning me has been a GIFT! The toxicity of many JWs was over the top. When they stopped talking to me, it felt like someone removed thumb screws.
Although I am not an advocate for DAing, I understand the need for closure that someone may have.
Let me add that fading without an explanation DRIVES PIMIS CRAZY! Without a target, they expend a lot of energy and ammunition so that is a good thing IMO.
