With gay marriage comes gay divorce

Just when you thought the sanctity of marriage might withstand a few more hits... K.O.:

It’s not a subject that marriage-equality groups tend to trumpet on their websites, but gay couples are at the start of a divorce boom. One reason is obvious: More couples are eligible. According to a report by UCLA’s Williams Institute, nearly 50,000 of the approximately 640,000 gay couples in the U.S. in 2011 were married. (Another 100,000 were in other kinds of legal relationships, such as domestic partnerships.) The marriage rate, in states that allowed it, was quickly rising toward that of heterosexual couples: In Massachusetts as of that year, 68 percent of gay couples were married, compared with 91 percent of heterosexual couples. Another reason for the coming boom is that while first-wave gay marriages have proved more durable than straight ones (according to the Williams Institute, about one percent of gay marriages were dissolving each year, compared with 2 percent for different-sex couples), that’s not expected to last. Most lawyers I spoke to assume that the gap will soon vanish, once the backlog of long-term and presumably more stable gay couples have married, leaving the field to the young and impulsive.

If gay marriage is morally wrong, how does one classify gay divorce?  My Catholic brain is imploding.
