Sounds like she was checking your temp again, Mary... or some might call it a "touch and go"...
It was a perfect opportunity to open the doors to see if you are pursuing others, by asking you about your "new look"...
Pretty much impossible to tell if she was hoping or fearing that you might be on the prowl...
Although if she didn't sound "disappointed" (like her comment about you being surprised at her question), then you may have played into her hand by indicating you are still available so she still has her safety net...
