I wonder what part of the post sleepy didn't read?
Anyway, just a thought, maybe he is JUST flirting with you and has no intention of wanting to take it further. This can happen, as flirting is a nice thing between two people, but it doesn't always mean you want to go beyond that. I have female friends I flirt with, but with half of them I would probably run a mile if I got the chance to go further because that isn't what I want from them.
Unless you get a really clear indication that he is trying it on with you, I'd just leave it.
