Does he not like me anymore?? What do u think?

K so there is this guy who asked me out a few months ago.... I didn't even know his name so I said no... Then I figured out his name added him on facebook and we started chatting with eachother.... He still liked me ALOT according to all of our friends.... Then he got a mutual friend to ask me out for him and I said not really but then idk what happened and I said yes... So we have been going out for 4 days but it has been a long weekend so we haven't seen eachother... I was just talking to him on FB and I asked him how he was and he said "ah ok how about u?" then I replied "pretty good.... Why only ok???" and he said it's complicated, then I asked what was complicated and he said " here I gtg" and logged off... What does this mean?? Does he not like me??? I am gonna see him at school tomorrow so I need a little help... What do u think about all of this???
