I just had a thought.

It seems to me, there's a flaw in the whole EN thing, and that is that they are not "weighted" to each other.

For instance, providing financial security is extremely difficult to achieve; and is it fair to lay that squarely on the shoulders of one spouse? Is it fair for one spouse to say they require this to be content, yet not act in a manner to achieve it?

And take sexual fulfillment. Some might say it is a rather simple thing to proffer up for a total of 45 minutes a week. Surely easier than providing financial security.

But yet, these things are all treated as if they offset each other.
