Frankly, it sounds like she did you a favor.
Of course the measurement inconsistency might be a product of guys telling her what 9 inches is...
Either way, she sounds like a nutter - you can pretty much guarantee that when you say "Not to be shallow, but..." then there is some seriously shoal-draft thinking in play.
"now I ain't sayin' she's a Gold Digger..."
PS - any further communication with her MUST include pics of your new Benz, deluxe condo and whatever swag you can gin up - "Thanks again for the blow-off, just spent our date budget on a new Rolex, I really like it."
