Whats my status with her?

I've been friends with this girl for well over 5 years now, we drifted apart for 2 years, but recently got back into contact over facebook. I commented on her status and she asked me for my number (this was 2 months ago), and ever since then we've been texting, mostly small talk. Although she developed this pattern of texting me pretty much every morning just to say things like "morning". I got the nerve to tell her that I missed her, and she replied with "aww I miss you to" (this was last Thursday) and since then things have been awkward to say the least, since then she has only texted me once. We spoke once on fb yesterday, and she asked me to help her with an issue she was having with a friend, which I did, she then said "thanks your the best brother". Today she sent me a fb request listing me as her brother. She also has a boyfriend (long distance), who she's never met, yet she puts these statues on fb recentley " At school.. _____i love you so much, after this morning being so happy we are together makes me relise that im deeply in love with you and nothing will change how i feel :)" and " At school.. I love you ______:) 5 months :) i miss you so much i cant wait to get home and call you :) im spending the whole day with you and no one else :) hehe you mean the world to me :) 03/09/2010 " (she posted this after texting me the entire day). Does she have feelings for me or am I just a brother to her?
