She's either stuffing the feelings down to pretend everything's ok (you're the enemy in a way- she won't show weakness to you if she can help it- she needs to convince you and herself that this is the life she wants and everything is A-OK, including DD), or she's not feeling it yet and some day, weeks, months from now, it (hopefully) will hit her and you'll have moved on to a better place by then.
Remember that: "revenge is a life well-lived" that someone around here keeps saying. I love that. You work towards that- let her stew in her guilt she hasn't recognized yet that will someday have a much bigger effect than if she felt it now.

When the men on the chessboard Get up and tell you where to go; And you've just had some kind of mushroom And your mind is moving slow; Go ask Alice... I think she'll know.
