I do think that many WASes do say those things during one of their moments of clarity and honesty. I believe that your W is telling the truth here. Sometimes those things do slip out.
Lady Karma has an elegant way of teaching our WASes life's lessons through difficult situations, events, and incidents. It will take several accumulating sequence of events and incidents that sometimes hits the WAS in between the eyes regarding their choices to blow up their M's and families.
No, I do not think that "it is finally sinking in" for W. Not quite. However, I do see that she's seeing glimpses of it and she isn't liking them at all. Instances like this usually produce spewing from our WASes because they're angry with themselves and then try to turn around to assign the blame on the LBS to make themselves feel better. It's elementary, my dear Watson.
If you stay out of your own way, then those incidents will take care of themselves. We all have Lady Karma to thank here. She's loving, but stern.
