Not interested... or something else?

So recently I've been talking to this guy on YouTube. On his page you can see how long ago he logged in. So we've been messaging back and forth for like 2 weeks or so. He always takes 2-3 days to respond AND I go on his page to see if he's gone online but not responded but he hasn't even gone online. Whenever he DOES get online he responds. Btw we haven't met but we do live in the same state, just a few hours away and we're both in college. That's just a random tidbit. So do you think he is interested or just talking to me to be nice?
