I think you sitting still re the R is just right. This is about Andy getting thru the mess he's made, and figuring out what he's losing in you.
IMHO, your interaction with him was perfect. As you've noted many times in your sitch, he responds much better to positives than withdrawal or negatives.
BTW, I've had a sneaking suspicion that he is trying to undercut your book's story with the presence of OW2. My prediction, tho, is that OW2's free will is going to do in his charade rather quickly.
