I know what you are saying and that is what I always assumed. That she had left because of the unprompted, unjustified and utterly aggressive posting of other members here. It's enough to exhaust anyone. I often not dare to tread on some threads because that exact reason.
I've learn to just ask for information and never express opinion.
Don't bother to ask her to come here just to talk to me. There's no reason at all to risk her happiness by dragging her back just to say hi.
I know - and yes I have been in contact with her and know she is fine - she was just done with CAF I guess - she fought a lot of fights for our shared values here so am sure that this was just a point of her own mental, spiritual health.... I understand, as I know you do - sometimes you just have to take a break - that is when I retreat to our group, and keep the posts there about the things we share...
