just be her friend and like todd stated, use the bible (isn't there an awake article that recently came out?) or as web-toed said direct her to that organization.
BUT if she doesn't take the help, and goes back to the guy (as some do) jsut know its SO awesome of you to care and you did your best as a friend.
...did your best as a friend and as a servant of Jehovah.
