I remember when my divorce was final. We'd been separated for almost four years, so it was pretty much just a paperwork formality, but it still brought forth an upwelling of difficult emotions and bittersweet memories.
Therefore, I think a pseudo-Hallmark card is in order. Picture a lavishly textured paper, fray-cut at the edge like the finest linen stock. On the cover is the most beautiful sunset you've ever seen, and the words "Wishing You Nothing but Happiness" on the cover. Now, open your card, and read this verse:
"The road was long, and filled with bumps
But you were tough and took your lumps
The hell with that, now...off your knees!
Its time to catch up on postponed sleaze!"
Seriously, my condolences on what has been lost, and my encouragements to both of you for the future and all it holds.
