“Nevertheless, in the majority by far of situations a marriage on the brink is repairable with the efforts by both parties.”
BOTH PARTIES. you stated the most important part. If one party sees nothing to fix, or does not want to fix themselves, it will not work. THATS the important part of making a marriage work-BOTH sides have to work to make it last. If one side demands the other to change to the image in their head or to live them the way they are because they won’t change, is that really a marriage that should be fixed?
