Are wedding vows unfair against men?

We went to the perfect midsummer wedding of my wife’s god-daughter in Norfolk this weekend. The service was pure Book of Common Prayer, omitting only some of the longer prayers and the woman saying ‘obey’ and (I think) ‘serve’. The service states the theological nature of marriage (‘signifying unto us the mystical union that is betwixt Christ and His Church’), and then its purposes. These are 1) children, ‘to be brought up in the fear and nurture of the Lord’. 2) as ‘a remedy against sin, and to avoid fornication’. 3) for ‘the mutual society, help and comfort, that the one ought to have of the other, both in prosperity and in adversity’. I found myself checking off how many of these concepts would win the assent of most people in modern Britain. None of the religious stuff, of course. No duty (as opposed to desire) to have children, or to have them in wedlock, or to bring them up godly.
