"Do not deprive each other except perhaps by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control."
--1 Cor 7:5
You're half right. It is his own "lack of self-control," but the Bible makes the other spouse responsible for not encouraging and enabling this weakness. Once again, you seem to be buying into the popular "Christian" tripe that it is always the man's fault. I used to think that, too, until my "Christian" wife had an affair and justified it on the grounds that I wasn't doing enough to make her ecstaticly happy all the time (despite trying to do so 24/7/365). It caused me to have to re-think everything that is commonly taught in Christianity about marriage. Much of it is horribly un-Biblical, and is designed to appeal to feminine forms of lust while rightly castigating masculine forms of lust.
Of course, I'm sure that has nothing to do with the fact that in our culture, women have taken the spiritual driver's seat in the marriage, and are responsible for deciding which church to attend, etc.
If you have been exposed to that cockamamie opinion, then I understand a bit more your extreme and emotional reaction to a movie that does nothing of the sort, but rather, talks about a man's beginning to understand his responsibility to his wife and home (as defined by Scripture).
In the movie, the husband becomes the spiritual leader, does he not? Isn't that a good thing? Isn't that Scriptural??
Well, even the Old Testament had an interesting idea, both the man and the woman involved in an act of adultery were equally guilty, and both equally deserving of the same punishment, if caught in the act by sufficient witnesses.
