He said he'd invite you over but his house is a mess. My guess is, that means he's married. And, that he was hoping you'd say, that's okay, we can go to my place (and have sex). But you didn't.
You start kissing a guy you've just met in a bar and you don't understand why he expects to get lucky? You don't "get it"? Well, I would bet that he's thinking the same thing.
Look at it from this perspective...a woman walks into a bar alone (with a bit of a buzz on, no less) and without hesitation, approaches two guys then begins dancing & kissing the first guy who shows her attention....frankly, it sounds like the woman is not only "willing" but "looking" for a hookup just as much as the guy.
If you're looking for a "connection" that involves emotions rather than physical parts, it's best not to obscure your intentions and reserve the kissing until after you've at least had a date with the guy.
On the bright side, at least your naiveté didn't result in your being attacked in the parking lot.
Thanks - makes sense now that it's the next day :)
