Girls I need your advice. I'm crushing on a female friend but I'm a girl too.?

[extraordinary]

So i have a friend who i've been friends with for a year and i basically started REALLY liking her and i'm a GIRL too. there are a couple very subtle signs that make me believe she could possibly like me too but i'm not quite sure. Like for instance, she would often text me she misses me and one time she texted me "miss you <3" after I just saw her the day before. and on valentines day she texted me happy valentines day with a bunch of emoticons and then she took a screen shot of my text msg and uploaded it to her instagram that read "<3 she made my day. #loveofmylife." before she put anything up about her boyfriend. she also like took a picture of me once at school because she thought i looked really cute and also uploaded that to her instagram as well. she often says things to me like "you're cute." I even caught her staring at me once while we were at the bar getting drinks. from the corner of my eye i saw her looking at me so i turned and we made eye contact for a few seconds then i smirked and she smiled quickly and looked away. by the way she knows I'm bisexual.

so about the part where she has a boyfriend. she recently told me that they're not "together" but still talking. i feel like they've fallen out many times so i'm not sure how that's gonna go. but yesterday she texted me after she woke up about our summer plan to california and then she tweeted on her twitter "it's weird how fast things can change." not sure what that meant
this is what i would say to her. http://s17.postimg.org/u7jc00ucf/Screen_..._42_AM.png
