Does she like me? I'm 13?

haha! you got banged? lol. Well, it seems like she might like you, but seeing that she has a boyfriend makes it difficult...hang out with her at your house one time and start a tickle fight (girls love those! lol) and find an opportunity during that tickle fight to kiss her! Yes, I said kiss her! That way, she knows that you like her and if she likes you, she'll keep kissing you. After you two are done kissing, then ask her what that means you two are now. Good luck!
