It means exactly what it means. Stop p*ssy footing around it. It means that the man is the head of the household. And if your husband puts his foot down on a matter, you should respect it as his wife. Because you married this man, you should have enough respect for him to let him take on this role when need be. A good husband will not be a dictator. A good husband will not bully you. A good husband will always take his wife's feelings into consideration. A good husband will not be yelling out commands every day. For some reason, this is what women think when they hear "submissive".
Say a man and his family live in one city. The man gets a job offer in another state. The man earns $80K in the old city. This new job will pay him $130K. The wife doesn't want to go, doesn't want to leave her home, doesn't want to uproot the kids from school. The man consults with her then says we're moving Is that him being an evil dictator or is that a husband doing what he thinks is beneficial for his family in the long run?
Good example to dissect.
He may not be being "evil" per say, but he is being a dictator and acting in self interest disguised as otherwise. You forget that money is not everything. Whos to say that uprooting those children from friends and family and dropping them in a foreign environment will be the best decision? That is something that should be agreed upon between both parties, not forced.
