Does he want something more than friendship?

I met a guy a few days ago who was visiting from out of town. We basically just hooked up, and I thought that would be it. But he ended up staying the night. We ended up spending a lot of time together and he stayed for two more nights. I showed him around the city, we went for dinner, etc, etc. he kept on saying how much he likes me and how he thinks I'm such a cool guy, and so on. But then he had to go back to the city where he lives which is more than 1000 miles away. Anyway, this has never happened before when I've hooked up -- it's hasn't happened very often at all -- but I think I like this guy a lot. If he lived in town, I think it could have turned into something serious. He asked me to go back with him to his city for a few days, but I couldn't tell if he was joking or not (and I couldn't right now anyway).

What was that all about? Why did he insist on spending so much time with me if he lives so far away? He clearly wants to be friends, and he clearly likes having sex with me, but does he want something more? Or are there guys who like to get really close to the guys they hook up with, like a short-term boyfriend experience?

I ask because I kind of want a relationship, but I almost never meet guys who I like to that extent (it hasn't happened in years). I know he's far away, but I am very mobile right now; if he was looking for something serious, it could work, potentially.

So...

Should I just forget about this guy? Should I tell him I like him in that way, and see what he says? Should I just wait for someone else to come along (as I had been doing for years)? Is this all just a bit silly? I just want advice.

I'm 22 by the way, and he's 25. Don't know if that makes a difference.
