Oh wow. And here I thought you were 13 or something because of Tingalz video of you (At least Tingalz said it was you) lip-syncing Chop Suey. Lol.
A. Never did that.
B. I only ask because, this is a lot... wait. Who am I talking to?
What the forget!? Stop using the same avatar damnit! You're gonna confuse people!
Anway, the only reason I ask you your age is because this all seems to be a bit much for even 16. Go out and enjoy life, don't tell a girl you love her simply because you think you do. You're young and you have plenty of time on your hands for this sort of thing. What you should be doing is be more concerned with just plain having a good time and not stress yourself over some girl who probably won't matter in 5 years. Also, her replies back to you are also way too Soap Oprah for the age.
NINJA EDIT: Yes, I said Oprah on purpose.
