GIRLS HELP

So there’s this guy who asked to be my waltz partner for prom even though we never talked in 3 years. He was super shy but seemed sweet. Then suddenly… he didn’t show up to practice. No message, no explanation. I went all the way there and only found out from others that he wouldn’t be coming. I feel like it was disrespectful. Now I don’t want to go to the next practice and I don’t want to text him either.
