I'm gonna be honest..
Some girls like to have close male friends, so you could be getting the wrong message. BUT I think you should go for it. Just ask her out for the weekend, as friends, and if it turns into more, then there you do. Just take a chance. Good luck =)
You see thats what I was afraid of. However do girls often tell their friends about their crushes?
In PE we meaning (me, my friend, the girl, her friend) were walking and while I was talking to this girls friend out of nowhere she said "I know who Paige likes" (Paige would be my crush). I found it a bit awkward so I changed the subject and we continued talking.
I am in deep love with this girl, I hope she likes me back. My heart aches when I am not around her, minutes move by like hours and hours like days. I am going to have to survive this weekend without her 
If you ask me, you're building this up to way more than what it actually is. Just enjoy it, if it doesn't work out, you will find another girl some day. You will. I know it's hard to believe in high school, but it's going to work out.
Its my first real love 
ASK HER OUT OR I'LL RIP YOUR !@#$% DICK OFF!!!!
Seriously she wants you.
All you need to do is ask her out and not let her in your pants (parent trouble).
And if the parents find out and make a fuss, it'll become exciting. Who knows maybe she gets wet at the idea of going out with a guy while her dad is super strict and disapproving.
But seriously just ask her out. It'll be just like your current relationship except with more touching and innuendo and RELIEF!!!!
So do it. Or I will track you down and do it myself (I might not be kidding about this).
