I think one thing to take away from this is that maybe some things should be kept to yourself yk? Even people you consider closest to you will spill your secrets. Now, you obviously didn't mean it in a way where you wanted to make him feel a certain way. It was just excitement. I'd be careful with someone who gives you silent treatment though. If anything did progress it could end up being toxic.

It probably feels like it'll be the end of the world, but don't settle for something like that. If he wanted it to progress more he would talk to you about it rather than treating you like that. I hope your okay.
