NLT - IMHO, I think a very short and to the point note saying just what you said, you hope he is doing well, is enough. Don't include any other sentiments, don't include anything at all other than that.
It will show him you are not feeling animosity toward him. It will not be pushing your feelings onto him which he can't handle right now. It seems safe, but caring.
Take care.
