Did I ruin everything?

Well, if you told him that he was taking you, that is more than a bit rude. You should have just asked him.

But I don't think all hope is lost. Just find him and talk to him in person. If he tries to walk away, go after him. Explain to him that it was just because you have a crush on him, and you wanted him to take you, so you just blurted that out. But if he won't listen to you after persistent efforts, I would just leave the whole thing be after a while. Walk away if it didn't work. Because frankly, one boy isn't worth it. If he doesn't want to make things right, then he's not worth it. There are other guys out there.
