It seemed to me that the topic here was a wife’s obligation towards her husband and kid’s–when the husband is working and providing for the family. It didn’t imply that the husband doesn’t have similar obligations. He has a kesuva to fulfill, and the gemora does talk about the obligations of wife and husband to each other.
In order for the home to be built as one that the Shechina would dwell in, it is important for both the husband and wife to know what Hashem expects of them.
