Most people have heard of the seven-year itch. It’s the cultural shorthand, popularized by the Marilyn Monroe film of the same name, for the restlessness that supposedly arrives in the seventh year of marriage. The wandering attention. Boredom. The wondering about what else might be out there. And the temptation that shows up when the honeymoon phase is a distant memory and the reality of a shared ordinary life has fully settled in.

Here is what the research has been showing for some time now: the seven-year itch has become the two-year itch.

The timeline has compressed. The restlessness, the boredom, the drift that used to surface around year seven is now showing up significantly earlier and often before the couple has even fully established the rhythms of their shared life. Before children, in many cases. Before the relationship has had the time to develop the depth that makes it worth fighting for.

This is not a small shift. And the real-life struggle it describes including the temptation, the boredom, the quiet wondering about whether you chose correctly, is not the glamorous Hollywood version. It is disorienting and often comes with significant confusion and shame, because most people believe they should not be feeling this way so soon.

But the itch itself is not the problem. The response to it is.

Do Marriages Have an Expiration Date?

When Al and Tipper Gore announced their separation after forty years of marriage, the cultural conversation that followed produced a question that I have been thinking about ever since. Psychologist Susan Pease Gadoua, writing in Psychology Today, asked it directly: do marriages have an expiration date?

My answer is no. But with an important qualification.

A marriage, or any relationship, will not expire on its own timeline. It will expire if it is not tended. If it is not watered, fertilized, and given enough light. If the people in it treat it as a thing that sustains itself once established rather than a living relationship that requires ongoing and deliberate investment.

Forty years of marriage does not mean you are immune to what I call relationship drift. Neither does twenty. Neither does two. The length of the relationship does not protect it. The quality of attention given to it does. And when that attention lapses, gradually, quietly, without either person quite noticing when it began, the relationship begins the slow process of dying that most couples do not recognize until they are sitting in my office wondering how they got here.

The Relationship Drift Nobody Sees Coming

This is the observation I want to spend the most time on, because it is the one with the most clinical urgency and the least cultural awareness.

Drift is what happens when a relationship is not actively maintained. Not dramatic neglect. Not obvious problems. The quiet, gradual accumulation of ordinary days where connection was not prioritized, where the relationship ran on autopilot while both people attended to everything else life requires and put things before their relationship. That is relationship drift.

Drift looks like the couple who stopped having real conversations. Not because they stopped caring but because the logistics of a shared life crowded out the space for anything deeper. It looks like the friendship where the visits, laughter, and commeraderie became less and less and neither person quite knows when the distance became the default. It looks like the marriage where physical affection and emotional connection faded so gradually that neither person can identify the moment it became unusual rather than ordinary.

Relationship Drift is painless in the early stages. And that is precisely what makes it dangerous.

By the time most couples come to see me, the drift has been accumulating for years. One or both of them is on the edge of a decision (to stay or go) and the work required to rebuild what was lost is significantly harder than the work of maintaining it would have been. The good news is that most troubled marriages can be saved. The difficult truth is that arriving earlier makes that work substantially more possible.

The two-year itch is a signal. The expiration date is a warning. Drift is the actual mechanism. And the antidote to all three is the same: intentional, ongoing investment in a relationship before the situation becomes critical.

The Best Time to Save a Marriage

Is not when it is in crisis.

I know that is not when most people think of seeking help. The cultural narrative suggests that you try everything you can on your own first, and you go looking for outside support when things have become desperate. But this sequencing produces predictable outcomes because by the time things are desperate, the damage is deep, the patterns are entrenched, and the goodwill required to do the repair work is often significantly depleted. Sometimes it can be likened to doing physical therapy for an injury, but you did the wrong activities for your specific injury or in the wrong amounts. Or I have even told clients it can be like taking Vitamin D, when you are low in B vitamins. It may not make things worse and it may even feel like you are doing something, but it is not actually addressing the underlying problem.

The best time to address relationship drift is when you first notice it. Not when it has become a gulf. But when it is still a little gap or a small crack.

The best time to have the difficult conversation is before it becomes the only conversation left. The best time to invest in the relationship is when it is good enough that the investment can compound, not when it is struggling so badly that every measure of effort is barely holding the line.

This principle applies in any significant relationship. The friendship that has been drifting for two years is harder to repair than the one that has been drifting for two months. The working relationship where tension has been accumulating unchecked is harder to address than the one where the first signs were named, understood, and repaired early.

Relationships are living things. They respond when attention is given, and they respond to neglect when neglect accumulates. The two-year itch is not destiny. The expiration date is not fixed. Relationship drift doesn’t have to happen. And they do not wait for a convenient time to become urgent.

What the Itch and Drift Is Actually Telling You

When the restlessness arrives, and it does, in most long-term relationships, at various points along the way, the question to ask is not whether the grass is greener elsewhere. It is what the itch is actually telling you about the relationship you are in.

Restlessness in a relationship is frequently a signal about unmet needs. The desire for novelty, for deeper connection, for being seen differently or more fully than the current dynamic allows. These are legitimate needs and should not be dismissed. The question is whether they are being addressed within the relationship or whether they are being interpreted as evidence that the relationship is the problem.

Most of the time, the itch or drift is not telling you to leave. It is telling you that something needs attention. Like a plant with yellowing leaves, it needs attention, not to be thrown out. The relationship has been coasting when it should be moving. The relationship in front of you deserves more of your curiosity and investment than it has been receiving.

Less drifting and more rowing. That is the work. Not the dramatic decision at the end of the drift, but the daily, unglamorous, entirely available choice to tend the relationship before it needs rescue.

Your relationships do not have to expire. But they will, like any living thing, if it stops being nurtured.
