Assuming that other people knew of her extra-curricular activities they'd say lots of things about her ... and about her husband. Some comments would be bitchy, some would be righteous, some would be envious, some would be humorous.
It might actually say more about the people making the comments than about the woman herself.
I would say you' want a maid not a wife. Taking good care of you isn't enough, if she's taking good care of everyone else, she's either doing it out of guilt at home or she things your some kind of idiot to accept this.
