Yuck, Slowly, I'd be a wreck. So what are you doing to thought-stop, to stay with trusting NG, to keep your anxiety yours and not project it onto him? Is he being sensitive to you regarding his destination? IOW, is he saying/doing anything that shows you he is aware and sensitive?
Great job on the mirroring and explaining - and great tack to take, that you were just letting him be and not nagging. I'm glad he got it.
