Have you actually met her? That tends to come across as bullshit when I hear it.
You can choose not to believe it. I've known this guy for over 5 years now, I know his wife, I know his family. I know what he does for a living (too well) and I trust him.
Furthermore, he's let me read his POF account emails, and I've seen the photo this girl has sent him - unsolicited. He has met up with her a number of times, and lately he's lost interest. Reason? Because he has many others, and he says she's got a real loser personality (although pretty).
I haven't tried POF yet, and I know my success rate won't come close to his at all. First of all, (A) they fill his email box with unsolicited letters because he fits the entire combination to a T (caucasian, dark hair, not balding, 6'+, blue eyes, broad shouldered). This leaves them vulnerable to what he does next: secondly (B) he spends a lot of time writing incredible emails designed to give them exactly what they want to hear as he's an expert at picking out a person's needs, wants, weaknesses, etc (it's one of the main things he does in his job). He can string them along for ages and wrap them around his finger. For him, it's a total power game. I'm not the combination in (A) and I don't like the game (B), so POF success for me is remote.
