A woman’s obligation to her husband is too learn what his essence is and what his neshama really desires and help build him into that person. That is why women are blessed with bina–the root being “boneh” she has the capabilities to help build him.
The same goes for her children. She learns their ma’alos and chisronos, and guides and builds them to be the best they can be. Through this she too will be built and their home will be mekadesh shem shomayim.
She should also take the time to eat together with her husband.
And of course all the above regarding keeping home clean, herself clean and attractive. Clean can also mean kadosh.
