Abstinence works. You'll never believe me though. But research shows it works when people try it. In fact the chance of you having infidelity problems in your marriage, if you are not a virgin at the time of marriage, goes up 50X higher than those who are. So, something for you to consider.
Sanctity of divorce? I would submit that's impossible. Are you a man of your word? So when you marry and say "till death do us part"... were you lying? If you were, or if you just don't hold true to your word, there is nothing 'sacred' about it. You either keep your word, or you don't. You either follow through on your promise, or you don't. For better or for worse, in sickness and in health, means exactly what it means. Of course, no one follows through with what they say anymore, so it's expected that the word of most men is worthless. But there is nothing 'sacred' about being an untrustworthy liar.
I read an autobiography of a man named Alex Spanos. In the book he details the problems his mother and father had. But despite the fact they really didn't like each other, both of them made a choice. They choose to make family more important than their little issues. The result of that was Alex had a wonderful marriage, and instead of ending up in prison, is one of the largest real-estate developers in the US. In the end, being at each others throats is a choice. You either learn to live with that other person, or you selfishly choose to make what you want more important than the good of the family.
