Facebook help pleaseee?

Okay, so there's this guy i like.. I was looking at his facebook, since it's very un private, and i accidentally liked one of his photos. I clicked unlike super fast though. I'm not his friend on facebook, though. So will he get a notification that i liked it? I also blocked him right afterwards, just in case that he looks for me. Will he get notified?? And what do i do if he finds out?? He doesn't know i like him, but yeah, help me!! Thanks.
