If you are going to go, check the site Lotus gave you soon because the dates and locations could be a real arguing point for your W (it's too far, too long, etc.).
Let her know this, the presenting couple had been married for 40 years. The wife said she had bad a marriage and just accepted it that way. She said her only regret is that she lived so poorly for so long, when she could've been happy with her husband (as she is now).
I can't say my W and I will succeed for sure, on Sat there was one point I had to leave the room for a 2 minute walk because of some cultural and language issues that I couldn't handle. By Sunday, just one day later, I am so glad I came back, but the weekend is now over. I do, however, feel much more courage and desire to make it work.
As your W is the WAW, maybe (think carefully) you could let her know that you will not fight her over the D if she is willing to try the weekend with the post sessions? There was one woman who said on the last day that she was just glad she came at all, because she wasn't going to. Or maybe instead of MC.
The weekend was definately not about the past, but it included acceptance of the past. The discussions were based on what it is like now for H and W. Best thing compared to MC, there is no way that anyone will validate you over your W's POV.
