Oh, I'm sure.
Have a co-worker who's wife left him at the five year vesting retirement mark, had been squirreling away the mortgage money and intercepting the late notices for close to a year in preparation of running off with another dude. Little did she realize spouses don't vest until ten years. Karma, bitch...
I'm a firm believer of never marrying anyone who earns less than 80% of your pay, regardless of hotness. Making more than you is always a plus, but then it's on you to keep up with her pay because that shit goes both ways.
