The "Maybe" Guy

I am having a great time on a first date, I think we are on the same page and we are totally hitting it off. At the end of the date he gives me a hug and kisses me on the cheek (weird). And then he says to me, "We should definitely do this again sometimes, maybe." Maybe?! I say, "yes, I would really like that." He says, "yeah, maybe." Maybe, again?! Then he goes in for another hug and kisses me on the lips. Um...what's up with this "maybe" business? So then I walk to BART and he tells me to text him when I get there. 
I get to BART and I text him that I had a nice time and would like to see him again and he responds with, "thanks for the note, get home safe." Again, what? 
Later in the week he sends me a text thanking me for going out with him and wishing me a good week. Again, I say I had a nice time and that I hope to see him again. Nothing. The next day he says that he is going out of town and wants to see me the following weekend. Okay, cool.
We end up getting together for dinner and drinks. Date #2. We were having a great time, laughing and telling stories. At the end of the night he is walking me to the BART station and I asked him about the "maybe" comments from the first time we hung out. He sounded surprised and didn't remember that he said that and said that it could have been that he didn't think I wanted to get together again. And he said that it could have been that he was going on a big vacation and would be gone for a while. We talked about the "maybe" situation for a bit and he told me that he would call me when he returned from his trip.
He sent me a message later in the week and called me "kiddo." Who is this guy?! Morale of the story, it doesn't hurt to ask, even if it's weird.
