When I was a Junior in High School, this guy joined my school's cheerleading squad. His name was Jonah. Usually I prefer older guys, but for a freshman he was really good looking and always dressed nice. I was 16, only a 2 year age difference so it wasn't a big deal. I developed a little crush on him as a result. By this point in my high school career, I was actually pretty well known with people in my grade, as well as the senior class grade which Jonah's brother was a part of, as well as the Sophomores. And because my Mom didn't allow me to go off campus, I got to know the freshman too. Which included the cheerleaders. So needless to say, they found out I liked Jonah and pretty soon after he found out too. It was embarassing the first week because I hate when people find out I like them (at least when I was a teenager). I messaged him on Facebook that weekend admitting I liked him. He said thanks for actually telling me and that we could be friends but nothing more.
It got even more embarassing though because it took me a long time to get over him. Looking back on it now, it's because he was the first guy I liked after I had been cyberbullied online by other gay teens. So the fact that he didn't like me back felt like rejection that I couldn't handle. So most of that semester I was a mess because of him. It didn't help that everyone in the school knew, so everyone was in his face asking about me. When someone that is really well known in the school develops a crush on you, EVERYONE knows. It's like 1989 type of overexposure so he got really sick of me as time went on. And he had really bitchy friends on cheer that were in my grade. In December, with Winter Formal coming up, they manipulated me into wearing a thing over my shirt that was meant to ask him out to Winter Formal. I didn't actually do it...I chickened out...which in retrospect was probably the best thing for my sake, those bitches were probably setting me up to humiliate myself but instead I turned it into a joke and took pictures with some of the sophomores.
He actually unfriended me on Facebook in 2011 for awhile. We patched things up, and I did eventually get over him, but we never really ended up being good friends. There was a wall that we never really managed to break.
After I graduated, he came out of the closet a year later

- I was like I KNEW IT! So that annoyed me too.
The last time I saw him was at his high school graduation in 2014. We took a picture and I pretty much felt like I was finally free of him. Clean by Taylor Swift makes me think of this whole thing, because honestly, knowing he was no longer going to be in SCV actually made me feel free of him because I no longer had to make an effort to be friends with him. He's now at USC and I've moved on completely. He's living his life and I'm living mine.
He was the last major crush I had as well. I've never let any other crushes I've had since get to a point where I couldn't be friends with the dude.
