Never answer a booty call after midnight. This is a healthy rule. Any booty call made after twelve o'clock at night is being made by someone who is drunk. Which is fine and all. Getting your drrrrrnk on is fun. Inviting an adventure partner over to play naked patty cake is also fun. But booty calls made after midnight are generally made by people who probably have the beer sweats. Then you know what happens? They don't answer the door, because they "fell asleep." Or rather, "passed out with their head in the toilet."

Oh, hi. This is just me, doing the Lord's work. Don't answer a booty call past midnight.

That this dude recognized that he effed up is a good sign. He might not call you back, because if he's a human with a heart, he's probably humiliated. You're going to have to give him some kind of subtle "green light." Next time you talk to him, laugh off that one night he "fell asleep" and left you at his front door. Jokingly mention how you'll give him one more chance. It's a joke! Ha, ha! But it's not. Everyone deserves a second chance, except for murderers, war criminals, and Ponzi schemers. Gently remind him how your feelings were hurt but if, in the not-so-distant future, he wanted to perhaps call on you for adult playtime, he can. So long as it's before midnight.
