I haven't contacted a boy I like for a long time. He asked me if I was there at one in the morning. I'm already asleep. I asked him what happened the next morning, but he didn't reply to me.

It is possible that this boy knows that you like him a little, so he has feelings for you, so he sends you a message in the middle of the night to greet you. As a result, you missed the best opportunity. It's okay. If you really like him, you can contact him. Don't let this relationship go. You have to work hard by yourself. Really can't. That's another matter.
