(Please correct my English!)
A good husband or wife is different depending on countries. However, I think that the most important thing is treating their own husband/wife and family with respect and caring. Otherwise, our life turns to tough and hard time.
Also, from my personal experience, both husband and wife having a work is good way to keep good relationship. The problem of money could be serious, if when something happens. To eliminate future anxious of economy and to have a respect each other, having work is one of the good solutions.
Although husband and wife are family, they shouldn't forget that the partner is not servant nor their own stuff. To treat the partner as an individual person is the way become a good husband/wife, I think.
