Good comments. Another fact that is often ignored is that the more sexual relationships are based on ephemeral attractions, without any bond of lifelong faithful marriage, the more anger and violence is likely.
Every relationship has problems. When two people have promised before God to remain faithful and loyal, they will often try harder to work things out; they have a higher purpose to remain together than mere sexual gratification.
When sexual attraction is the main reason for the relationship, and it inevitably lessens in the fireworks department, or someone gets fat, or there are children who may be viewed as accidental, or there is unfaithfulness, anger ususally results. What happens next? Often violence. And women start it or participate in it more often than is reported.
To sum it up, chastity before marriage and fidelity after is the best remedy for peaceful relationships. (It also helps for people not to drink to excess - drugs and alcohol are often a factor in spousal abuse.)
I hope you meant, "the best recipe for peaceful relationships"! :-)
This is a lesson our society seems dead-set to learn the hard way...again.
