Chatting at a bar… what does it mean?

I (27 F) was chatting with another guy (40 M) at a bar tonight and we were getting along pretty well, making jokes with each other, looking at each other pretty intensely. I was so hoping he would at least make out with me or ask for my number. After chatting and hanging out for an hour or so he said he was gonna go to another bar to hang with his friend. Didn’t ask for my number or anything, and no attempt at a kiss. I could’ve sworn there was chemistry. Was I delusional? Or was he trying to be polite? Idk. I need help. I thought he was soo attractive and cool. I don’t think I am bad looking either.
