He left me on read :(

So I have a crush on this guy that goes to another school. I know him because he goes to the same church as me. I went to the football game friday night (my school vs his school) and when he posted on his story the next day, i slid up and said good game yesterday!” just to be nice. instead of a thanks, all i got was a “who r u” and then when i told him who i was, he left me on read. that hurt my feelings & i cant stop thinking about it. also i can’t stop thinking about why he didn’t reply and all the things he probably thinks about me...

was i being creepy? am i overreacting? idk how to feel, i’ve liked this guy forever. all i wanted was a simple “thanks”
