I know you are prepared either way T2, and so do the rest of your friends. I can't imagine this last chance separation frustrating any of us, but even if it did, who cares? It's your life/marriage/choice.
I also know you have put plenty of thought into this. And effort. I honestly don't see you having regrets that you didn't try everything... which is what I also want to be able to say.
I like your plan to write it all up in a packet. The "Last Chance for a Great Marriage With Me" packet.
I'm hoping the time away helps your W realize what she is about to lose. Bust On, my friend!
M: A really long time. Crisis: 5 years. She's still worth it.
