HG, I hope you aren't all cracked up over this. They will probably have a divorce party, to set up a new household for the one moving out.
Actually if all is "equal" in our justice system one of them will be paying spousal support for until the other remarries.
I bet their victorian in JP will command a pretty price, too.
No, maybe one of them had a child, and they'll spend the next couple of years trying to use the pro-marriage amendments passed in other states to get their ex-partner removed from child custody, like the lesbian couple in Ohio.
I wonder if they are finding that non-intercourse sex just doesn't have the same power to bind two people together as one.
