Interesting note: I just remembered that my W started the C session today with "Well, I guess things have gotten to the point where they can't get any worse"
I'm glad she thinks so, but there really is no such thing. Things can always get worse. I like the way both of them are picking up on holding on until Retrouvaille. She sounds like she will have the open mind that's needed. The willing heart will come if the mind is open. Look at the Retrouvaille logo -- it is a lifeline hanging on a cross. It's an excellent image. I stared at it all weekend as they spoke.
It is hard to commit to forever. You are exactly right that all she needs to commit to is trying to make the marriage better. You have made a lot of headway. Sometimes a crisis is a good thing because it brings things to a head and makes you change. And change is necessary. As they say at Retrouvaille, if nothing changes, then nothing changes. Which means, if you don't change, you cannot expect to see any changes in anything else.
