My best friends are all guys at my school - and my closest friend, the boy I shared pretty much everything with, including my not-so-nice face and history, I had a crush on once upon a time. He didn't think of me that way, and we settled into friendship. Relatively recently, he told me he had feelings for me more than friendship, and did I want to let this be more than that?
Bear in mind, he's going to school in that country, I'm going to school in Scotland, and the likelihood is, we're probably not going to see one another (although stay in contact). Yeah, I made the changeover, and I can say I honestly don't regret it at all. He's still my best friend but he's also more than that - a friendship foundation is fantastic to have, (if you can get over the awkward, 'oh my god, I shouldn't be kissing my mate' phase) I'd say 'go for it'. if you guys are good friends, that won't change because of going further.
