Thanks for the background. I'm sympathetic to Snopes but it's very un-Snopes-like for them to leave this context out of their post.
I clearly don't know enough about the background to make any call on who's right and who's wrong here.
They divorced because David was having affairs with multiple women, ostensibly even using Snopes money for prostitutes. Of course even if not the primary cause of the divorce, a husband-and-wife business is going to make the divorce messier.
