I first thought the girl might be a little immature until you called someone a pedophile.
So, that was my first and second thought. I take it she's younger than you and you will soon be out of her life (if you go away to college). Just don't take her too seriously, because her mind is in a totally different place than yours, trust me, girls don't even find out they are lesbians until after they realize they don't like guys. I think. Maybe. I have no clue.
