Back to the original subject. This is why you don't marry a woman that's in it for the security or money. No matter how good she looks, there needs to be an equal attraction. Sure have fun with them up front but never let it get serious. And if you get the slightest hint that she thinks she can use it as leverage, run fast. I'd guess 95% of these women showed their cards before marriage but the guy was too entranced to heed the warning.
I can't imagine having to get my wife drunk or spend money on her in order to get some. Must really suck to be stuck in that trap.
