Move on.
Tip, What you are saying when you open a girl on facebook is the same as her seeing your face/body for the first time. So its worth the time and effort to check grammar, and make sure its easy to read. Otherwise you are setting a terrible first impression. Unless it is a girl who obviously doesn't give a flying fuck about the English language.
I also changed what you said, but used your same idea. I would of said something along the lines of ;
" Hey, i see you are in my friends list, but have never spoken to me. Are you trying to be my stalker?
"
