The Brits used to have a specific word for this, which isn’t in wide use any more. They called it a “Pash”. She is, as you say, one of your best friends, and clearly she has a lot of traits you admire, so your recently-adolescent body and hormones are very likely interpreting that in a sexual way. Being bi-curious at your age isn’t at all unusual, but from what I’ve been told by both lesbian and gay friends, if you really did “swing that way”, you wouldn’t be this unsure about it. I’d probably try not to come on to her in an obviously sexual way, if I were you, because it would be a rotten thing to lose a friend over a crush. Some basic flirting would give you a good idea if she’s even open to the possibility of experimenting, but be prepared to accept it if she isn’t responsive
