I have this friend I used to know from work and she was really nice to me and I thought we were friends. So when I heard she recently made a FB account and I sent her a nice message. Because I haven't heard back in a few days, I decided to click "add friend" and request to be her friend. When I went back to her page a few hours later the "add friend" button is no longer there. When I checked my activity log page, It doesn't show that I requested to be her friend at all. I can see the usual things I saw before on her page except for the "add friend" button...

HOWEVER, when I went on a fake account the "add friend" button IS there! What's happening? Is this an FB error or is it me...and she blocked only me because she doesn't like me and doesn't want to be my friend?
