Sounds that way to me, I have the same wonder about my W. In retrospect, it seems like her change of heart came after her cousin (2 years older) died from cancer, and her mother was diagnosed with liver cancer.
Of course, with DB'ing strategy being "keep it light, be positive" and all that, it really doesn't offer the opportunity to explore that further with her. Or, it could just be denial. Sorry I don't have answers for you, I'm just as confused.
