How did you get the impression that he would be thrilled with you moving to NoCal? He still seems deep in his fog and is very erratic with this thoughts and emotions. He has been hanging out with you and D a lot, says he misses D after one night. Yet he's okay with D moving several hours away?
Try your best to get to a peaceful, detached place and think through all of the implications with that move.
