Will she ever love me, or did I go too far?

You're thirteen. You're not in love. You're infatuated but not in love. Don't get stuck in that trap. It'll lead to heartbreak.You're "in love" when you're in striking distance of being ready to propose. And that isn't in three weeks after starting dating. That's a long time after starting dating. Be patient, don't get too into it, because believe me, guys do some stupid things to themselves when they realize they can't have the girl they're infatuated with. You don't want to go there. You don't even know if you like the person for real. You're just buzzing with hormones and it's mixing with the things you'd like about her otherwise. You have to really get to know someone before you can say you're in love. And you're not in love if they don't love you back.
