"Where my family comes from, the problem is circumvented by having your legally recognized wife and having your "other wife"."

I don´t mean competing sexual partners of the same man. I mean several married or formerly married women competing to be the mistress of the same household.

You pointed out that for a boy, marriage means becoming a master of a household, and acquiring a house is precondition of marriage. Meaning a culture where for a boy, marriage means more than getting laid - even if the family means and house could accommodate it, a boy would not be married if it means continuing to live with his father as his father´s dependant.

It is widely acceptable for adult but unmarried daughters to live in household with their mother, as a dependent working under the mother´s orders. What happens to the girl at marriage, besides getting screwed and likely soon knocked up?

Would marriage require that she moves to a new household with her groom, one in which she is the only woman and as such the mistress of the household? Or is it a possibility that she´s moved into a household where she is NOT the mistress of the household, because the groom continues to live with his mother and the mother-in-law now holds authority over her daughter-in-law?
