being the 'DUFF' and the platonic girl

Now on the other hand, I do have a few guy friends who are also nerds. But I'm always that one friend that they all keep as platonic - which really confuses me. Am I really that bad that nobody wants me as anything more than a friend? One of my best friends is a guy and I love him so much but I could never tell him bc I know it wouldn't work out - he's just come out a relationship where he got dumped after a year and a half bc her parents didn't approve. He's still heartbroken over it and says that he's not looking for a relationship or dating anyone bc he'd have to go through the talking and the meeting up, but in the 3 months since his breakup, we've done all of that. We legitimately cannot go a day without talking to eachother. I've been there for him the whole time. At the same time as his break up, i found out that the girl who was supposedly my best friend was going behind my back and messing around with the guy I liked. Understandably I was also heartbroken over that. The guy I like now has been there for me through everything I have been through in the past 2 years. I just don't know what to do bc I know he will never go for me. He is amazing and gorgeous and I'm so out of his league it's not funny. He makes me so happy, and I make him happy too. He supports me and I support him. But there is no way he's gonna like me back or anything bc he loves me as a friend and cares so much about me that way.

I know this probably sounds stupid, but I thought I would say something bc I just hope I'm not alone.
