In my office, There is no such thing as "good" of "bad", only what works and what doesn't work. If not doing housework works for you in your situation, don't do it. Or would you ask for help with the housework. And why are you so eager to label yourself a "bad wife". Perhaps seeing a therapist could help you sort some of this out.
Certainly not. But you might be messy. Keeping you surroundings clean and organized is important for over all functioning. Maybe you and your husband could discuss division of labor and change your current allocations. Maybe you need help and support to make changes that improve your mood, or to change your housework patterns.
