Shy guys along with Facebook?

[Bella]

This is an odd situation, I've known this guy for two years now. He's shy but last year I told him I liked him but he said, "okay" and that was it. This year we've gone to a football game and we listened to music together and we also went to a concert and now we've been talking but it's been over Facebook. I usually start the conversation but we usually talk all day and we talk about our favorite bands and things of that nature. We usually end the conversation at two in the morning and sometimes at school we'll talk but mostly online. The thing that worries me is that he knows I still like him but we've been talking so much now and I don't know if he likes me or not. Any advice on this? Please and thank you!
