Most divorces are initiated by the female, not the male. You knew that, right?
One of the things Protestants accuse the Church of is replacing biblical practices and replacing them with pagan ones that the early Church absorbed from the Greco-Roman heathen culture of the day. I think that is almost all wrong - BUT . . .
If there's one place where the Church rather explicitly took on a pagan cultural norm it is in the notion of mandatory monogamy. The Romans were very serious about monogamy (although they allowed divorce, which I understand was no uncommon). St. Augustine addressed the issue, and to paraphrase he basically said that polygamy was allowed to the ancient Israelites because they needed the increased fertility but now we don't need the increased fertility. Also, God doesn't require polygamy so it's not a question of basic faith and morals so it's one of those areas where we Christians can and should accommodate the larger pagan culture as we, in effect, need to pick our fights carefully with them.
My favorite Protestant theologian, R. J. Rushdoony, wrote (I think correctly) that some limited form of polygamy should be allowed as a concession to human frailty, much as we allow divorce. There isn't much difference, after all, from a man marrying one woman after the next and paying child support and spousal support to his exes as we have now and polygamy whereby all would agree to share the man sexually as well as financially.
