Solid stats are hard to come by, but it's estimated that of people who marry 40-50% will go through at least one divorce during their lifetime. There's definitely no stats here but anecdotally I'm inclined to believe that women who self identify as "a bitch" and enjoy kicking men to the curb are able to get past that 50% hump without breaking a sweat.
I would imagine that a guy who immediately wonders whether a woman has been divorced is more likely to be divorced than the woman he's wondering about.
