This was from an AskReddit thread where they were talking about biggest sexual regrets and there was a stream of responses about guys being clueless to women's advances. This one stuck out to me a bit:

This just happened to me last night! Was flirting heavily with a girl at the bar and as it was time for her to go, I walked her out to her car and we chit chatted a bit. The last thing she said was "shame the night has to end like this" and drunk, still partying me said "It's cool! We can hang out next time" and went back into the bar to get more shitfaced.

I wouldn't have even thought twice about this interaction but this guy thought he was oblivious to this women's advances/he could have had her. What do you all think? Also, how do you go forward in this situation, if this is indeed an advance.
