When many couples first start out, they are sometimes willing to agree with each other to keep their relationship intact. They see it as a compromise where they can make a good difference, but it might not hold up over the years. Fighting with each other is a solid path toward divorce, so learning to disagree with a spouse without arguments and tears is a better way to keep the relationship from becoming bad enough that it affects every part of their lives.
Setting aside a disagreement on an issue has worked well for many couples, but there can be occasional flares of danger when it arises from an outside source. Those who have made their peace with a partner will often find that refusal to discuss the issue in their home or the presence of their spouse works for them. It might eventually come to a point where they have to thrash it out between them, but their differences might have mellowed over the years.
