The supposition that it is always possible to learn to love the other person is as ridiculous as the supposition that people are static.
> If both people are in agreement that they might change and get divorced later before the marriage begins, then fine with me.
Everyone who gets married knows that the possibility of divorce exists and roughly what divorce proceedings entail. How does making these details explicit as opposed to implicit help anyone?
> There is a stigma, but it's not on divorce; it's on someone who goes back on their word.
I would wager that very few people are as hot-to-trot as you are on the notion of honor in contract literalism.
> My life is simpler, more enjoyable, and happier if I associate with people who will keep their word at any cost. Maybe your experience is different.
It is. Honesty is valuable, but by my way of reckoning there is little honesty in the practice of enshrining outdated guesses about the future. A promise made without implicit limits is a lie.
