If he was staying out for the night at someone's house, what difference does it make? The whole "to know they're ok" is something you do with children, not adults. He had no excuse for being 3 hours late when he should have been 25 minutes away, that's inconsiderate. Still, if this is something happening as often as it apparently has, you two just aren't on the same wavelength. I'm not sure there's any point in apologizing when you see him next, best to just move on.
