Guys: Why would you ignore a girl's message?

Anonymous
I added a guy on Facebook 4 days ago (he's a friend of an old friend of mine. Different school, but not far from mine. We've never met btw) and messaged (inbox-ed) him first the same day cause I thought he was really cute and seemed nice. We started having a good conversation (asking & answering each other questions) and he even said "you look really pretty by the way just putting that out there :)" all of a sudden. After that he was talking about his future plans, and asked about mine. I replied (it was almost twice as long as his previous reply) but didn't ask him any question in that particular message. He has been online but hasn't replied and it's been 3 days...?
