Well you certainly seem to be detaching well. It's not about responding, it's about doing it without emotion. THAT is / was the hard part.
I know it's hard on the kids going through all this. They are remarkably resilient though and adjust very quickly. I do think it's a shame that W is asking them to keep quiet. Although it does show that she cares what you think. She isn't HALF as detached as you anymore.
I hope that whatever happens by Friday that you remain in the place you are now, that's the best place for you whatever happens.
