Does she like me more than a friend?!?

It seems like u 2 are in love! :) Most girls hide the fact that they're in love with a good friend because then if it doesn't work out, their friendship will be awkward. Since u know this girl since a very young age, it seems like you're destiny was to be together. The fact that u have so much fun together, makes it obvious that u like each other. So here is my advice. Ask her out in a sarcastic way. If she takes it seriously, she'll say yes. If she doesn't then she'll joke back. If she feels uncomfortable, she'll change the subject. If she rejects u, then joke about it so things won't be awkward. Hope ur relationship works out, buddy!
