Dating

What's the difference between hanging out, dating, and seeing someone?

I met this younger guy last Tuesday. He's really cute and he approached me. We ended up talking a couple of hours that night and set up a date for Friday night because he didn't want to leave without setting up a definite time to see me again. He text me a couple of time the next day and we ended up going out that night. Night 3 he wanted to come over and watch a movie with my daughter. (She's a teenager so he's not a pervert and it ends up I work with his cousin so I knew it was safe to let him come over). Then Friday, day 4, he took me out to dinner and spent the evening watching the Olympic opening ceremony. Saturday night we only saw each other for about an hour due to work schedules. We were talking and he was telling me about his ex some of his dating so I took the opportunity to ask what we were doing. Dating, just hanging out etc. His response was that he didn't really know and didn't know what he wanted. I know this is only day 5, but I've seen him every one of the past 4 days at his initiation. I just don't understand men! Can anyone give me some insight here?
