I wondered. You seemed to have moved into a situation much like mine. My now X was always saying "how come we are so good together" or "things are better now than they ever were" and then Blam....divorce city. I really cannot figure out why the WA thinks this is some sort of answer.
It sounds like you handled it really well and certainly paved the way for a post-D relationship. Hopefully you are able to fare better than I have post-D. I think I've moved backwards from where I was just before D. Maybe the X gets more comfortable with the D over time. I don't know. But at any rate you have a headstart on your continuing R. We'll have to compare notes.
P.S. I'm sorry to hear that your W was determined to get the D. You handled it so well that I forgot the apologies. I hope all it does is help your W see her way back to you.
