He didn’t want a hug?

Anonymous
I’ve been talking to this guy and we’ve been on two dates so far. Our last one was Saturday and I thought it went pretty well. Anyway today I saw him around campus and I went up to him and we stepped aside and talked for a minute. As I was about to leave I was waiting for a hug but it didn’t happen.
So I was like “idk whether to give you a hug or not”
he was like “oh okay”
And I was like “are you much of a PDA person”
and he was like “no not really”
so I said “no problem, see you later” and walked away

Is this a red flag? Why wouldn’t a guy want a hug? We’ve hugged before in more private areas (parking lot, park bench).
