Hmm.
Well, now that so many women are in the workforce and the number of women who get college degrees are equal to or have surpassed the men getting degrees, in this economy it's not unheard of for the woman to be the only person in the relationship who is working. I don't know that I would call this gender role reversal though, since a woman working does not contradict her still being a woman, nor does a dad who is home with the kids while he is looking for a job contradict his still being a man.
Maybe a CDer in this situation would look at it differently though. :p
