“Perfect Is The Enemy Of Good” — Of course most people have heard this before. In my personal case, it should have applied to my marriage. My ex-wife would be bothered by anything that was not perfect. If everything was not in order, then I had no right to sit down and watch a football game. In reality, many things were very good. There was lots of money, I spent lots of time with my stepson engaging in his development, etc. But that last little bit of marginal utility needed to be drawn from me.
This issue seems to be more common with women. Probably much of it is because of how they are naturally built. In addition, the self-esteem based preteen years, combined with the heady teens and twenties lead them to believe that the world is there just for their asking. So why not desire the best: they are worth it.
How do fellas react to this? In the medium and long runs, not so well. Instinctively they see that the extra effort that they put in is often not really doing much (i.e. low marginal utility), and they resent this. This leads to all sorts of bad things, fights, divorce, etc. She ends up with much less than she could have had by moderating her demands. In my case, the ex-wife did not make out so well in divorced life. Still, she controls her own destiny now.
