Guys Only: What does all this mean...?

Ok so one day I walked into subway with my step dad and i saw this guy and we just started talking or whatever and then once he and his family got there food they left.. So I was kinda interested in him but all I knew was his first name and where he worked. oddly enough about a month later I find him on Facebook. I add him and he adds me back almost immediately and we start talking for a bit then he asks me for my number. So now we've been texting and such all night and then all day and night and so forth... we discuss how we felt in a way like he said that he hated that he had to leave and wanted to stay longer just to talked to me and how he wish he got my number, he even says that he think I'm very pretty. But Im confused mostly because he wants to hangout and go see a movie and he says were just hanging out or whatever. I think its a date... I mean it is just the two of us at night...but ok. LOL, anyway what do you think about all this? Can you tell if this guy is interested in me or likes me? or does he just want to be friends and is super flirty in a sense? HELP! I don't get it!!!! :/
