Ok so there's this guy that I went out with for legit only a day, but that was a year ago. A few months ago, we started talking a lot and hanging out a little bit and one of his best friends told me he liked me a lot. At the time, I liked him a little but not as much as I think he liked me so I told everyone I didn't like him. We still talked a little after that, but then we just stopped, and he told me that he was moving on. Now we're in high school and he doesn't like me anymore but I like him. And it sucks because I had the chance to tell him I liked him when he liked me, and I feel like I blew all the chances I had with him. But I also never told ANYONE I liked him so no one knew, and I feel awful and I really like him now... what do I do?? :/

Start talking to him again and see how things go.

I'm trying but he's not in any of my classes and I hardly ever see him :/

And I want to tell my best friend that I like him but she's wicked close with him and I don't know why but I'm afraid to tell her

Well since he is the one who left you, you should let him approach you. If he wants you back he will, if he doesn't, there's no point in your telling him anything.
