True. Manipulative people suck.

So...you're scolding sampling bias while pointing to this one website as evidence for your accusations of sampling bias? Hmm....

Or Jeff is just bad at choosing anonymizing usernames :P

Yeah, I'd have to agree with you on this one. The only thing complicated is his premeditated cheating. He had to know what he was doing if he lied about his girlfriend to this other girl, and now he's trying to cover it all up? Pathetic. Guys like this give the rest of us a bad image.
