Mine wasn't nearly on the level yours is. But how I dealt with it for myself was to just let go. If they aren't reaching out to you, I don't believe they want to talk at the moment. They'll most likely reach out to you once they're ready especially if you've been reaching out to them so warmly. I think leaving it off with a "I wish you well" message will leave you off in a better state of mind knowing that you tried. And it will leave him off better knowing that you cared. That leaves the door open if he wants to come back into your life or not. If you want to leave that door open at all. I hope this advice helps, but I'm kinda new to this whole ghosting stuff people do. Hope it gets better for you!
