gma - I love that song too!
Good for you dbell. And you are building your new life now - you're already moving forward instead of staying in limbo.
When I first joined SI, I used to get confused about XWW or XWH. I always found myself wondering if it meant they are no longer wayward or if it meant they are an ex-spouse or if they can't be wayward anymore because they are an X. Yes, my brain was soup in those days.
I think you can call her any old thing you want. I always liked STBX. After it's final, simply X or XW.
