Can't get her out of my head :S

It is pretty hard to get your mind of a girl that you just can't stop thinking about.
I would just try to find some other things to do and if she wants to call or text back she will. It has been awhile you said but then you say she has not updated her FB in a week...and that is pretty unusual for people in 2011 anyway so I would not exactly "give up" on her but I would stop calling and texting her.
I think that she may be on vacation or something and just doesn't have her phone or maybe it fell in water or anything could have happened.

That is just my guess because she hasn't updated her FB which is huge but at the same time do not get your hopes up and just do your own thing. Its not like you and her were together so there are lots of other girls out there and if the time comes where she does call or text you back then you can do the same to her if you still have feelings for her.
Life is short. Do not be just waiting around for one person that may be ignoring you even if its what you want right now or think you want...later in life you will see that there are girls that really will not ignore you and some even will be to clingy that you will just want them to stop texting and calling you ;)
