AIO for feeling like I missed my shot with this guy at the bar last night?

So I went to a post hobby meet up yesterday night. We all met at a local bar and sat and talked for about 2-3 hours. The guy I ended up sitting next to went to get an extra chair and pulled out a chair for me to sit. I ended up forgetting my drivers license at home, so I got a non alcoholic drink. He asked me what I head having and I told him and he offered to get me a drink. I accepted and we talked on and off and with everyone else we were sitting with for the rest of the time at the bar. He was having a beer and I’ve never had beer before since I’m not much of a drinker , so I asked him what it taste like and he said I could take a sip out of his drink. I drank a little and then I asked him a few more beer related questions just to be engaging and keep the convo going.

He smelled really good and I wanted to tell him that to try and show interest, but I didn’t know if that would be weird lmao. My friend said I should have said it, but of course, my nerves got the best of me.

This is where I fucked up. As we are all getting up and saying good night, I go to tell him thank you again for the drink and that I really appreciated it. He said it was no big deal at all as he put his hand on my shoulder and sigh…..I fist bumped him since everyone was doing it to each other.

I feel like shittttttt for not going for it and my friend told me I was being super oblivious and that it was obvious that he wouldn’t have a gf or say not to me giving him my number.

Thankfully, I see him again in two weeks when our group restarts or sooner if I go to a match and he’s also playing this weekend.

AIO? Was I being oblivious or was he being nice? Advice?
