"then I'd have to admit to him I thought he wanted me to invite him and risk him saying, "what? no, not at all, I don't want to go to your graduation." And then I would feel humiliated and rejected. "

and *when* the time comes.... *if* you want him to, you can always toss it out casually; "You know, graduation is X day, if you wanted to, you could consider yourself invited" and leave it at that.
