While Paul writes that the husband is “head” of his wife, whatever it means cannot negate the fact that he is also his wife’s Christian brother and bond-servant, according to Galatians 5:13.
“For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another.”
Galatians 5:13 ESV
