Agree on Western Europe, likely worse than even here. Eastern Europe and Russia are better. But Asia is still likely the best overall. But obviously the key is the specific families - have there been divorces in those families. My wife has 7 siblings, not a single divorce in something like 220 years of combined marriage, and no talk of divorce, at all. I doubt any of them wants to be the first either...they’ll stick it through, even if it means some struggles, at times.
I think marriage always involves struggle. In my personal opinion, those that don’t involve struggle likely involve a partner who is somewhat withdrawn and who won’t ‘fight’, no matter what. You’re absolutely right about sticking it through. If by the end or your life you can say that you have by your side someone you’ve shared a large amount of life with, who knows who you are, and truly loves you, you have been successful in life.
