Not all marriages end in paradise.
Sometimes, they dissolve into purgatory or even worse.
Sometimes, though, you can choose a partner who very quickly becomes someone entirely different. A glutton, for example. Or a bigamist.
A woman in Australia recently married the love of her life and became Mrs. Keyet. Excited that she was now Mrs. Keyet, she changed her relationship status to "married."
She might have wished she'd changed it to "harried."
For no sooner did she ask her most important friends to share in her joy than she received a Facebook message: "Hello, new Mrs Keyet. How can you be Mrs Keyet when I am still Mrs Keyet? From the old Mrs Keyet."
As Australia's News.com describes it, the new Mrs. Keyet wasn't amused. She demanded that the old Mrs. Keyet check the official marriage records.
For Mr. Keyet had informed the new Mrs. Keyet that there was no longer an old Mrs. Keyet and hadn't been for a long time.
Indeed, it is said that Mr. Keyet had told the new Mrs. Keyet (and the person officiating the new Keyet wedding) that his previous marriage had been ruled invalid, for there was no official trace of it.
Sadly, the old Mrs. Keyet gave the new Mrs. Keyet a copy of the marriage certificate. A search showed that it was still valid.
So the new Mrs. Keyet left the one and only Mr. Keyet and asked that a court annul her marriage.
Mr. Keyet, though he had attended both weddings, didn't turn up for the court hearing.
He reportedly sent a text that read: "I think I've put her through enough hurt." Which some might regard as a slightly belated sentiment.
This isn't the first time that Facebook has proved to be the altar on which a marriage finds itself a sacrificial sham.
Just three years ago, a woman logged onto Facebook to discover that her husband has allegedly enjoyed a fairytale wedding recently -- just not to her.
And then there was the curious case, just a year ago, when a woman received a Facebook friend suggestion that offered the picture of someone who allegedly was, well, her husband's other wife.
In all these cases, it is husbands who appeared not to feel comfortable with full disclosure.
One can only look forward to the day when Facebook demands to see marriage certificates before anyone can claims official Facebook "married" status.
There again, Facebook has come to see the family as a fairly painful entity.
Its latest Facebook Home ad suggests you stare at your Facebook friends on your cell phone under the table at dinner, rather than listen to your parents' pointless droning -- assuming they are your parents, of course.
