Ok I know some of you are curious and have asked.
Anyways I went out with B. for the first date on last Sunday. It was just dinner at a local bar and grill. Conversation was great, flowed really well. We talked about everything from hiking to classical music. Towards to the end of the date he said he wanted to take me to Seattle Symphony's performance of Carmina Burana. I said I was interested. He paid for dinner, I did offer to split.
Despite the great conversation and fun I had I did not feel any spark.
The next day I looked at the schedule for the Seattle Symphony and realized I'm on call for most of the performances. I texted him to tell him. I suggested the opera on Friday because I already was going but he had other commitments.
Wednesday he texted me asking if I wanted to see the symphony on Thursday (next day). It was Richard Strauss. I said yes, but suggested we get dinner beforehand nearby. We agreed on a restaurant, I made a reservation.

Unfortunately, Thursday was completely crazy at work I ended up staying late unexpectedly. I did text him to warn him that'd I be about 30 minutes late, he called the restaurant to shift the reservation. I made it to the restaurant at the shifted time but he was late because he couldn't find parking.
Conversation was good. I could tell he really liked me, a lot. But looking at him, I just didn't feel anything. Nothing carnal to be blunt. He's not bad looking, he's 48 (I'm 41) in decent shape.
Again he paid for dinner, I still offered to split.
Walking to the symphony he held my arm, opened doors etc. Total gentleman. I should mention he's originally from Mexico, so I'm sure it's cultural.
Symphony was nice. He gave me a ride home because I would have either cab or bus it home.
I panicked a bit at my place, and leaned over and gave him a very QUICK tiny kiss and then bolted out the door.
Five minutes later he texted me saying "You are awesome!!!"
So now I really don't know what to do. I had a ton of fun with him, but I don't feel anything, just a friend vibe. Not even idle curiosity.
I haven't heard from him since Friday when I texted him saying the opera was going to be really long. But I've been busy too.
I don't want to lead him on. Friends are split between saying see what develops versus cutting it off.
