I would do it anyway. Only thing that stops me from ever sending friends requests is fear of rejection. But don't take it personal if she does deny your friends request because it's possible she would not want to be FB friends with anyone from workor she wants to be FB friends with her family only and close friends. But only send one friends request and if she never accepts it, do not send her another one.
