Really confused with this girl?

this girl right, a couple of months ago she always flirted with me, i kinda liked her too but but i didnt really prioritize her...... eventually she stopped. then after some more bad luck w/ girls (3 girls i le know i liked em and they were taken) i started liking her more, ALOT more and then guess what-she gets a boyfriend. but it only lasted 2 1/2 weeks and shes single now. but during that time she wasnt i got closer to her, and started letting her know that i liked her a little bit. then i couldnt stop staring in class and such and yea i let her catch me and every once in awhile shed say, under her breath "why are u staring at me?" but never out loud. then one day, i left a comment on one of her myspace pics in a bikinithat said "u look beautiful" and and when i saw her that day in one of our classes she stared at me for a full minute, then said "nice picture comment btw" continued on add details

This girl can't make up her mind and you're stuck in the middle confused as freakin hell! Ask her if she's serious about you or not and tell her that she should make up her mind quickly because she doesn't know what she's missing out
