SR, I don't post this often because a lot of the people on the boards are women and I don't want to look like I'm rooting for them to fail, but the divorce research shows that a divorced woman's standard of living tends to drop more than a man's and the vast majority of them report feelings of extreme loneliness.
It's the grass is greener thing. Your WAW for whatever reason wasn't totally happy and it couldn't be her fault so it must be yours. So she likely built up this fantasy in her head about how great life would be without SR.
So she acted. And here's where it gets hard. Most people, me especially, really have a problem admitting they are wrong.
So even if she has found the grass isn't greener on the other side, she's unlikely to admit it to you. It'll take something really drastic.
Now, as I type those words I see my own life in it and it still doesn't help the pain that much. Only time has helped.
