Hey Hope. I think should play some of it by ear. Say you miss him if it feels right and it doesn't feel like it will sound as though you are trying to manipulate him. Show him you have heard him, but hear him too, you know? Validate what he says then, don't try to bring up things he said in the past unless it is comes to that. If the convo doesn't get to the points you are thinking about right now, you don't have to make sure you say them. Just save them for later.
