There is a form of betrayal in marriage that is often ignored for far too long. It does not involve another person, and it does not always come with obvious conflict. Instead, it shows up in the gradual loss of sexual intimacy between a husband and wife. Because it happens slowly and is so common, many couples assume it is something they simply have to accept. But in my experience, when this part of a relationship is left unattended, it almost always carries consequences.
It is true that sexual desire changes over time. Physical aging, hormonal shifts, illness, fatigue, and even how a person feels in their own body can all affect interest in intimacy. These are real and understandable factors, and they should not be judged. However, what concerns me more is not the change itself, but how couples respond to it. When the change is ignored, minimized, or avoided, distance begins to form.
In many cases, there is also a shift in attention.
John Gottman speaks about what he calls negative comparison, where one partner begins to look outside the relationship, even if only in thought, and imagines that someone else would be more attentive, more understanding, or easier to be with. This does not always lead to action, but it does change how a person shows up in their marriage. When attention moves outward, whether that be for work, addictions or personal reasons, investment at home decreases. And both emotional and physical intimacy begin to weaken.
One of the most important aspects, often overlooked, is the impact of rejection. When one partner reaches for the other and is repeatedly turned away, it does not remain a small moment. It affects how safe a person feels in the relationship. Over time, they may stop initiating, not because they no longer care, but because they are protecting themselves from being hurt. As this pattern continues, the relationship can begin to feel less secure, and both partners may start to withdraw in different ways. These repeated experiences, even if they seem minor on their own, accumulate and shape how each person experiences the marriage.
Some couples will say that they are able to maintain a strong relationship without sexual intimacy, and in certain seasons of life, that may be true. However, intimacy is not only physical. It is one of the ways a couple expresses closeness, commitment, and mutual giving. From a Christian understanding of the person, the body is not separate from who we are; it is part of how we express ourselves. This means that physical intimacy, when it is present in a healthy way, communicates something meaningful about the relationship.
This does not mean that couples should approach this issue under pressure or with a sense of obligation. In fact, that often makes things worse. What is needed instead is honesty. A willingness to acknowledge that something has changed and that it matters. The couples who are able to move through this well are not those who avoid the topic, but those who are willing to talk about it respectfully and patiently. They focus less on blaming each other and more on understanding what has contributed to the distance. They remain curious about each other rather than defensive, and they take responsibility for how they have each contributed to the dynamic.
What I often remind couples is that problems in a marriage rarely resolve on their own.
When something begins to fade, whether it is communication, respect, or intimacy, it requires attention. Not urgency or panic, but intentional discussions. Whispering to yourself ‘ I really don’t care’ is a sure sign that something is off. Why? Because in marriage, you should care. It is one of the most important commitments you have made in your life, so how can you not care?
If you find yourself in a place where intimacy has lessened, it is worth addressing, even if it feels uncomfortable. Not because something is irreparably wrong, but because this part of your relationship deserves care. In most cases, the first step is not complicated. It is a conversation that is honest, calm, and grounded in a desire to understand rather than win.
