Does this girl like me?

okay so I've *known* this girl since seventh grade and she's always been friendly towards me. that same year she quickly asked me to a dance, but my stupid, antisocial past-self merely said "huh" and she looked away and said "nevermind". (fast forward to ninth grade) now over the past few months I've been making a conscious effort to become more outgoing and spontaneous. A few months ago this girl started talking to me even more than ever; sayiing "hi *my name*" and "*my name*, i love you!" in the hallways; asking me who i liked and has since then asked me for my number and signed my yearbook saying I <3 U :). do you think she likes me? because to be honest, shes cute and if she does, the feeling's mutual. what do you think? oh yea im a straight guy who is well aware of his oblivious-ness. just to filter out any unnecessary answers.
