I'm going to add a different twist to this discussion.....
My husband and I have been incredibly happily married for nearly 40 years. We are both Bible-believing Christians who believe in the inerrancy of Scripture (different from 'literalism' which doesn't account for cultural and literary dimensions). We believe that the Scripture is the inspired word of God.
That said, we have had, from the beginning, a mutually respectful, egalitarian marriage, in which we both submit first to God, and then to each other (read the verse before the "submit to your husband" verse in Ephesians 5). We believe that we live, both as individuals, and as a couple, not under the curse, but under Grace. We also believe that God has one will for both of us, and if we are both seeking His will, there is no need for a 'boss.'
We have a peaceful, orderly marriage with very little conflict, and none of consequence, in which we are equals. There has never been an important decision in 40 years on which we didn't agree. And there is no sin in our seeing each other as equals.
I think there is a lot of damage done by oversimplifying the 'rules' and trying to get every individual and couple squeezed into the same mold.
Perhaps a bit more Grace is called for in discussions on these matters..... ^-^
