Well, young man, in this society it is standard for a man to be married to one woman at a time. Other cultures do allow men to take multiple wives, though I have no !@#$ing idea why any man would want more than one, but, I digress, you'll learn in due time. Anyway, back to the story...the guy, we'll call him schmuck, was married to one woman, though separated. Schmuck has met another woman, the love of his life, and he married her without divorcing wife #1. That is frowned upon.
The only part that Facebook plays in this is it was used by wife #1 to discover that there was a wife #2. You need to read more.
Well, yeah I get that it's wrong, but why is it headline news? My dad cheated on my mom, that didn;t make the paper.
