Tell tale signs of if you've encountered her are if she begins to talk about how she lives with her ex-fiance who still wants to marry her, despite the fact that they broke off their engagement in 1995 but stopped having sex 1 year before you begin talking with her. Another sign is that she tells you you're the first person that she has feelings for over the internet.
