On a good day (and you happened to catch me in one of 'em, Bob), I'm convinced that if we can only hold on long enough, we'll get there.
Have you read Mattie's latest posts to me? Lily's another one. They've been on the "dark side" themselves, and here they are trying to save their own marriages.
Just hang in there until you're back in sync with your SO.
It's a long haul, but in the end, it's worth the ride.
