Each marriage has to be judged separately, and we never know what's going on in another person's marriage.

In this quote, Mary Wesley emphasizes the idea that every marriage is unique and should be judged on its own terms. She suggests that it's impossible to fully understand the complexities of someone else's relationship from the outside. Marriage is often a deeply personal and private bond, and what works for one couple may not work for another. This reflects Wesley’s recognition of the individuality of relationships and the importance of not making assumptions about others' personal lives.

Wesley also acknowledges that we can never truly know what happens behind closed doors. The complexities and challenges within a marriage are often hidden from public view, making it difficult for outsiders to understand the dynamics of the relationship. This speaks to the privacy and intimacy inherent in marriage, which cannot be easily interpreted or judged based on external appearances or assumptions.

The quote also suggests a sense of respect for the privacy of others. It encourages people to refrain from passing judgment on relationships they are not personally involved in. Wesley's perspective implies that each marriage has its own set of challenges, experiences, and nuances that can only be fully appreciated by those within it, rather than by outsiders who might only see fragments of the whole picture.

Ultimately, Wesley's words convey the importance of empathy, understanding, and withholding judgment when it comes to relationships. By recognizing the uniqueness of every marriage, we are reminded that what works for one couple may not be applicable to another, and that true understanding can only come from personal experience and respect for others' choices.
