Why is this happening😞😖

So a couple of weeks ago I was playing truth or dare with a bunch of girls and one boy, that one boy was my crush, and people were trying to figure out his crush, I wanted to know too, but i also didnt... in the end only one person knew who my crush liked, I was pissed off bc I knew she wouldnt tell anyone, and I was also extreamly depressed. Anyway I figured out who it was like half a week afterwards, and bc I already had my suspicions ur didnt really bother me much then, but recently its started bothering me alot, and like whenever I talk to him I question what to say based on his mood, but lately he seems really annoyed with just me... what should I do..?..
