"Her tone in email and text while I've been gone has been very formal and cold. No idea why... detaching, confused, who knows. But today's emails, after I got back to her in the afternoon, had little inside jokes in them. She confuses me."

WHG - why does her behavior confuse you? You are detaching this week and she is trying to pull you back with her emails. First formal and cold, then when that didn't work, little inside jokes. This is clearly a reaction to your detachment and you should mark that as a positive, small as it may be.

"I have to say right now that I see no chinks in her armor and nothing but a full head of steam from her heading towards D. The brain part of me knows that she won't show me any second thought anyway, so looking for them is pointless."

She is reacting to your detachment. That is a chink in my book.

Act is if, WHG. Act as if!
