Like if they don't like people ( human beings in general) because they're are not a people person but they are tired of being harassed so they get plastic surgery.

Yes or no
Please explain answer

I just had a good, in my opinion, first date with a guy I only spoke to briefly online. Before we met, we only texted a little - about where we're from, what we do, our hobbies, just couple words, then scheduled a date. It wasn't the type that we would text all day and I thought that's how he texts which was fine.

I think we had some things in common, had what to talk about, spent a few hours together, it was pretty easy for us to talk to each other (I think). He's not the type to be flirty or very expressive, he is somewhat serious and reserved, we were just getting to know each other, there was no physical interaction or anything. The only thing, it was very late, so by the end I might've gotten a little quiet bc I was tired and I hope he didn't consider it disinterest. We were waiting for the train and talking and when the train that he could take came and I told him, he said "it's ok, I'll wait for the other one" - that we took together - I thought it might've meant he wanted to talk to me.

When it was time to say bye, he smiled, shook my hand (well I don't know, he did that at the beginning as well) and said smth like "it was nice getting to know you, let's keep in touch", I said the same.
Did he mean it or did he not like the date? He's a tiny bit shy and reserved, plus it also took him a few days to text me after I gave him my number through the dating app (he asked me out, I said yes, gave him # to keep in touch outside the app, he texted only a few days later), he was probably talking to someone else. Maybe he's just not the type to text all the time and will text me to schedule a date when he decides he wants to? Or he's talking to someone else now but does want to see me again?

Or, I'm afraid, he didn't think I was interested bc I got a little quiet and bc of how I ended the date. In this case, should I text him and say I enjoyed spending time with him, in case he thought I didn't?

by the way, today is the second day since the date.
