America has turned into that couple that looks like it wants a divorce

Maybe you've known them. Maybe you've been part of one. They are often reluctant to admit they've crossed that line where there's really no turning back, but the honest observer can see it plain as day. They've had it with each other. However long they've been married, however good at might have been (or seemed) at a given point in the past, it's painfully clear there's no pulling it out of the fire at this point. All that's left is for them to admit it - to each other and to themselves - and then to start the process that everyone who's been through it tells me is pure and utter hell.
