My DB coach made an interesting point the last time we talked. If your H is still upset, then he is still emotionally connected. Anyone who is truly "done" would be indifferent.
I know we are all cheerleaders here, but patience is really important. It may take him leaving, moving, and falling on his face to realize what he has lost, and that has not happened yet.
