For the sake of privacy, I'll name my friend Ryan and the girl Jen.

So, it started when we entered 12th grade. we had a reshuffle and OP, Ryan and jen and we became classmates. Me and ryan are close friends since Grade 11, because of a certain game we play. when we had some people join our friend group and Ryan met jen. Ryan pretty obviously liked jen, but he didn't make any moves and jen thinks they are only friends, and ryan seems to be okay with it. I even asked him if he likes her but he quickly changes the topic. Then on Feb 14th, valentines day, i asked her out for a friendly date, and she agreed. It was only a friendly date, after school, but Ryan saw us and he was furious because we said we were going home but we instead, had a date. It was only a friendly date, but ryan seems to not understand it, and not believing me because i sent love letters &amp; stuff. I got mad, because he acts like they had a relationship, but in reality they are only friends. we still don't talk to each other to this date.
