I understand your point. But I still think that an honest person, entering into a vow instigated by Love, and living by it with Love, will come out well in the end - in terms of personal growth and spiritual development - no matter that the other person goes ‘off the rails’.
“Law” doesn’t make a marriage, and neither do the ceremonies and approvals of priest, rabbi, etc; and Law nor ceremony can keep it together.
Would you want to have somebody ‘stuck’ to you legally or religiously, who obviously doesn’t love or want you anymore, and doesn’t treat you with respect?
Only love, respect, devotion, make a marriage. Nobody can ‘destroy your world’, if YOU live by love, respect and devotion. They may cause you difficulty for a time, but in the end you will move on and find new life - if you stick to your ideals, and learn from your experiences.
The reason marriage has fallen apart in recent decades, is because PEOPLE have “fallen apart”, in their principles and ideals. But nobody is stuck with that. We make new decisions and goals every day.

I think we have both explained our positions in detail.
