May I weigh in on this. I think you haven't factored something that is true for a lot of couples. And that is: AFTER you get married, to the person you WANT to be married to, when he has long been yours and you have long been his/hers; your heart simply does not see other people in a significant ways. Not in the way you describe. It doesn't occur to you to even compare because there is no reality in which they feature in your mind in that way. They are there in a non-threatening way. Your instinct is not to even compare them to your spouse because there is no comparison. He/She wins all the time. Your heart has a home. You admire others, get along with them, and see them, but they can't get past the checkpoints that your spouse got through. Marriage is not always this constant wrestling, this never-ending contestation. Your scenario below may be true in other cases. But it is also true that in a room full of phenomenal people, some can not see anyone better than their person because the impulse to compare doesn't even occur. They have arrived. That is also true of marriage.
