Just go to the Post Office and ask for a change of address card. Bundle up his mail with the COA card in there. You won't have to say a word, but the message will be loud and clear.
As long as the ow is present, he's still in replay. He's got quite a ways to go yet. His peeks out of the tunnel are just moments of clarity. They are when he remembers his life with you, but he can turn on a dime and dart back into the tunnel.
Keep doing what you are doing. You're handling it well. At this point in time there is little you could do to make or break anything. MLC has to run its course.
Hope is yours. No one can take that away. Just keep your expectations low or at zero to protect your heart.
