Sunny, I agree that 'congratulations' is not appropriate. Several of my friends have said that, but I don't think there's anything to celebrate. It's closure, but only in the same way a funeral is. Nobody congratulates you in a funeral, even if the person who passed was a horrible human being.
I'm glad it's been over a year of separation. It has given me time to process my emotions and move forward. I was ready to be 'uncoupled' at this point, and I told WH that he could move ahead with the D back in February, I think. I think the fast divorces are brutal on most people.
