I'm less concerned with the 'why' than with what my W is doing to change. If your W is taking her insight and learning how to validate herself and not seek external validation, for example, she's making a good change.
Also, you may want a specific answer, but you're not her, and she's not you, which makes it likely she'll give a different answer than you would.
What changes has she making? Is she committed to further change?
