Men or women are only reduced to behaving as children when they buck authority and are immature and arrogant. Children usually think only of themselves. Just because the man is the final authority in marriage should not cause the wife to act selfishly or irresponsibly. A humble woman can have great dignity in marriage under the authority of her husband. In my own observations it is the bitchy nagging bossy wife and the hen-pecked man who have lost all dignity and are childish.
"It is the glory of God to conceal a thing, but the honor of kings to search out a matter." Proverbs 25:2
