PLEASE NO ONE IS ANSWERING! Should I just try and not think about her like that for a while?

We're both 14 almost 15 and freshmen. I have a crush on my best female friend. This isn't the first time. I've had crushes on my female friends in 4th and 6th grades. Both sent my friendships with them spiraling into hell with them. Anyway, I've been friends with this girl for about a year now. We like all the same things and have so much in common. I just couldn't help but be drawn to her. Anyway, she has a boyfriend, and although I'm sure he's a great guy, I just can't help but feel an unconscious twinge of jealousy. I mean, social-wise, she and I are complete opposites. She is very popular everyone loves her and me I have social anxiety and I am very surprised she'd want to be seen with me in public despite her being possibly the kindest person I have ever met. I have social anxiety and my metabolism is a bit slower than most people's making me constantly embarrassed.
On Halloween I saw an old friend of mine who was a lot like me and our best friend (the three of us were all best friends in elementary school) social wise in elementary school. I hadn't seen him in a year because he moved to a different school before 7th grade due to bullying. He was very happy over there he had a girlfriend. I walked with him and his friends for a while (mainly sticking with him and his gf). I mentioned I like her and I didn't have a girlfriend (I forgot to mention she had a boyfriend possibly due to us making a run for it from drunk kids). His girlfriend had offered to set me up with single people she knew, but I declined. IDK if I should've taken her up on her offer I don't have a facebook and my phone is basically only a communication device between my parents and I (I have little siblings and sometimes my parents work a little later than normal). Should I set my eye on other girls for a while and wait for my crush/girl friend to break up with her boyfriend (he's an upperclassmen it won't last too long), or just ride it out on my own save for my best friend (the one who still goes to my school) and just be a good friend to her? Please answer I will answer yours I swear I will. Thanks.
