What does it mean when a guy says he misses me after first date?

Anonymous
I went on a date with a guy from online dating. We had texted a lot prior to first date, and in my interpretation, had developed pretty good connections. We had a lot of similarities in terms of interests and how we text (we both don't send one or two-sentence texts).

I'm not sure if this context matter: Prior to meeting, I had stated that I'm looking for a long-term relationship and he said he had intentions for long-term.

After the first date, he had said that he missed me and wanted to see me again. What does that mean? Did he "catch feelings" or was he emotionally attached to me? Or was he just infatuated and mistook that feelings for missing me?

I tend to assume it's his infatuation and he might've felt the same with other girls he's dated in the meanwhile, but I could be wrong in underestimating his intention.

Thank you for helping me gain some insights into this.

My question is what does "miss" mean for guys? Is there emotion in it or not? He said a few times that he missed me, missed my smile, wanted to see me again, said I'm amazing, etc.

I mean, how does a person miss someone already after one date? Is there emotion involved?
