Girls, I want vengeance on a girl who took my 3-year ongoing crush. How do I do it when nobody even knows I like him?

So in fourth grade this new student moved to my school and I liked him ever since. Now we're in seventh grade and in B-class together. However, recently a girl from A-class broke up with her B-class boyfriend and is now with my crush! The problem is not a single person knows I like him and if they did they probably wouldn't like that. He seems like a nice person to me and I trust him but I don't want to ruin our growing friendship. Also I am quiet and why and not so popular. But I just can't seem to let him go, and I am suffering from a desire for vengeance on this girl caused by jealousy. Not a day goes by that a think of my crush— and him with another girl. I'm not regretting seeking revenge, but I can't stand how many people approve of what's going on (yes, even the girl's ex likes it). Help me! I liked him first! What do I do?
