What does it mean to be a good husband / wife?
For me, being a good husband or wife is making the another one happy. When fight happens the couple should sit down and talking about their problem.I think it depend of each person.
I dont think exist a good husband/wife, each person should do something that other likes. If you dont like to cook and your husband/wife dont cares, okay. If you dont like to cook and your partner likes, you talk about that situation and find better way to continue to relationship.
Nobody become a good husband/wife. Or you are good person or dont. Is necessary to empathy and more love to build a good relationship.
