The Purpose of Marriage: How Couples Build Shared Meaning Together

The purpose of marriage, from a clinical perspective, is to build a shared meaning together that gives both of your lives more weight than either of you could carry alone. It is not the wedding, not the romantic feeling, not even the intimacy. Those are real, but they are downstream of something deeper. The purpose of marriage is the slow, sometimes invisible work of two people building a shared identity, a shared story, and a shared sense of impact on the world around them.

That is why couples who lose their sense of purpose often describe the same thing in our practice: not that they fight more, but that they cannot remember why they are still together in the first place. The argument is downstream. The shared meaning is the load-bearing wall.

This article walks through what shared meaning actually looks like in marriage, where it comes from, and how couples build it on purpose rather than hoping it shows up by accident.

What “Purpose of Marriage” Actually Means in Therapy

When researchers and clinicians talk about purpose in marriage, they are usually pointing at one specific thing: shared meaning. John Gottman built an entire level of his Sound Relationship House model around this concept. He called it Shared Meaning, and he placed it at the very top of the house, above trust, above conflict management, above friendship. The idea is that strong marriages do not just coexist. They construct a shared interpretation of life together: shared rituals, shared goals, shared symbols, a shared sense of what matters and why.

That is what people are really looking for when they ask “what is the purpose of marriage?” They are not usually asking a definitional question. They are asking a load-bearing one. They want to know whether marriage is supposed to feel like this. Whether it is supposed to be this hard. Whether the two of them have lost something they were supposed to have.

The clinical answer is that shared meaning is not a feeling. It is a construction project. And couples who do not realize that often spend years waiting for it to arrive on its own.

Meaning Starts With Your Shared Story

Every couple creates a shared story of their relationship: how they interpret the events that brought them together and what they believe about where they are going. Just over a year before this article was first written, Verlynda and I were preparing to leave on a year-long trip in our travel trailer. Having to create that vision for ourselves, and then explain it to other people, forced us into a process we did not realize we were in. Every time someone asked, “Why are you doing this?” we had to answer. And every time we answered, the story got a little more solid.

Any major life transition for a couple does this. So does the early stage of marriage itself. You are bringing two individual identities together and creating a new, jointly developed meaning that helps you make sense of your relationship and makes the future feel a little more stable[i]. The work happens whether you do it consciously or not. The question is whether you are doing it well.

One study looked at the stories newlywed couples told about how they met and dated. The content of those stories, and the shared meaning embedded in them, was a strong predictor of marital wellbeing[ii]. Three patterns stood out:

Storytelling process. Couples who told their stories collaboratively, with high agreement on the details, were the couples whose marriages held up well over time. Disagreement and conflict during the storytelling itself often suggested the couple had not yet built a strong sense of shared meaning. This is where you can actually watch purpose forming or failing to form: in whether the couple’s history feels synchronous when they tell it.

Storytelling style. Telling the story as a narrative with a sense of drama, rather than a flat list of events, also predicted wellbeing. The animation reflected investment. Couples who were genuinely interested in their own history were the ones who had something to invest in.

Story content. Attributing tensions or difficulties to factors outside the couple, rather than blaming each other, indicated cohesion and was linked to high wellbeing. Framing the story primarily around conflict and barriers, on the other hand, was linked to lower satisfaction. If the entire story of your relationship is defined by turmoil, it tends to keep generating more.

What I take from this clinically is straightforward. Couples who carry some sense of providence, destiny, or “we were brought together for a reason” tend to have a more meaningful story behind why they exist as a couple. That sense of meaning becomes a platform from which they can begin asking the next question, which is how they want to impact the world together. Whether you frame the source of that meaning as faith, fate, or simply a deliberate choice, the platform itself matters.

And in our work with couples, the pattern we keep seeing is that the couples whose first-date stories diverge significantly are often the same couples who, ten or fifteen years later, sit in our office describing a marriage that has lost its center. The early disagreements over “how it really happened” turn out to be early signals of the same shared-meaning collapse they cannot name today.

Four Forces That Shape Shared Identity

Shared story is the foundation. There are four other forces that act on shared identity once it forms.

Family of origin. How involved your family of origin remains in your married life has real consequences for marital satisfaction[iii]. Even as you build shared meaning together, you have to stay in touch with your individual identity and history. The critical move is that both spouses agree on what the right level of involvement is. I am not talking about enmeshment. I am talking about a healthy, marriage-centered approach to family relationships where both of you are reading from the same playbook.

Flexibility. Each spouse comes into the marriage with their own identity, sense of purpose, and expectations about what the marriage should mean. A couple’s ability to construct a shared meaning depends heavily on their flexibility, because the construction has to be collaborative[iv]. Rigid expectations on either side do not survive the collision with another person’s actual life.

Romantic versus companionate love. Couples whose shared meaning was based on positive relationship qualities like intimacy, satisfaction, and commitment were significantly more likely to have stable, satisfying marriages. Couples whose identity was based mostly on passion and romance were not[v]. Passion alone cannot sustain long-term shared purpose, because romantic love often does not last the entire length of the relationship while commitment and intimacy can. As we covered in our episode on the neuroscience of dating your spouse, this is not an absolute rule, but it is the dominant pattern.

Positive and negative meanings. Newlyweds are influenced by each other’s negative views of marriage (the things they believe make a marriage bad), but not by each other’s positive views[vi]. In other words, couples come into marriage with a clear, shared sense of what their marriage should not be like, while figuring out what it should be like takes longer. That asymmetry has clinical consequences. Couples often agree on what they are running from years before they agree on what they are running toward.

Expressing Shared Purpose Through Joint Ventures

Once a couple has built some sense of shared identity, the natural next question is what to do with it. One of the most common ways couples express shared purpose is through joint ventures: enterprises, projects, or causes that the two of them invest in together.

This podcast is one example. We started it as a joint venture and it has shaped our marriage in ways we did not predict.

When the joint venture is business-based, research shows that the love bond between couples grows stronger over time as they work together[vii]. Couples who build a business together create shared experiences, which can raise intimacy, even though work and family roles get complicated[viii]. Couples who do this well typically share three qualities:

Strong family values
High mutual trust and confidence in each other’s abilities
A strong commitment to equality in the marriage[ix]

The “joint” part does not have to mean each spouse owning half of the business operations. Sometimes one spouse runs the venture while the other contributes through household management, network-building, advisory work, or simply keeping the running spouse grounded[x]. Joint does not mean identical. It means co-invested.

Joint ventures also do not have to be commercial. They can take the form of involvement in your church, service to your local community, work on a school committee, coaching, mentoring, or volunteering. Some joint ventures build the life you want inside your family. Others create impact in the world around you. Most couples I see in healthy marriages are running both at once, often without naming them as such.

Sometimes the activity is shared equally. Other times one spouse takes over with the kids for an evening so the other can pour into something purposeful. Even though they are physically separated that night, the activity is still shared because both of them are invested in it.

Parenting as a Vehicle for Shared Meaning

For couples who have children, raising a family is one of the deepest sources of shared meaning available to them and one of the most lasting forms of impact on the world. As we have covered in earlier episodes on parenting for the benefit of your marriage, raising a family carries both positive and negative effects on life satisfaction[xi].

Day-to-day satisfaction often drops while children are young. Sleep, freedom, and bandwidth all shrink. But long-term life-meaning, the deeper sense that your life is contributing something, often runs higher in parents than in non-parents. Couples whose children have grown and moved out tend to score high on both day-to-day satisfaction and long-term life-meaning. Anyone who has parented young children knows the work is brutal, and most parents would also tell you it is one of the most meaningful things they have ever done.

Why a Healthy Marriage Multiplies Life-Meaning

A healthy marriage, even before you add outside projects or causes, can help people feel like their lives have more meaning. Intimacy is consistently one of the highest predictors of life satisfaction and life-meaning[xii]. Marriages provide intimacy, passion, and contentment, and these positive emotional experiences tend to make daily life feel more meaningful[xiii].

There are two effects here. A happy marriage helps you feel that your life has purpose, and it also helps individual actions feel meaningful even when life is hard, like when you are caring for young children[xiv].

This is one of the strongest arguments I know for investing in your marriage relationally, not just logistically. When you build a safe, secure, loving relationship with your spouse, that relationship becomes the safe harbor from which you can explore everything else: meaning, impact, legacy, parenting, work. When the marriage is not safe, an enormous amount of your energy gets pulled back into managing the relationship itself, leaving very little to direct outward.

Outside ventures can sometimes serve as a distraction from a marriage that is not going well. That happens in our office often enough that we watch for it. But even in that case, the question I would ask is: imagine how much more impact you could have on the world around you if your marriage were the secure base it was meant to be.

How to Start Building Shared Meaning Now

If your marriage feels like it has lost its sense of purpose, start with the smallest piece. Ask each other how you would tell the story of how you met if a friend asked tonight. See whether the answers line up. Notice where they diverge. That is your starting point.

From there, look at the four forces. How is your relationship with each other’s families functioning? Where are you flexing and where are you both refusing to bend? Is your relationship organized around intimacy and commitment or mostly around the early intensity of romance? Have you ever sat down and named what you both want your marriage to be, not just what you want to avoid?

Then look outward. What joint venture, however small, are you investing in together? It does not have to be a podcast. It can be a garden, a small business, a service commitment, a child you are raising, a community you are showing up for. Couples who are building shared meaning have something they are pointed at together. Couples who are losing it usually do not.

This is not abstract work. It is the work of marriage.

Frequently Asked Questions

What is the purpose of marriage?

From a clinical perspective, the purpose of marriage is to build shared meaning together: a shared identity, a shared story, and a shared sense of impact on the world. Romantic love, intimacy, and even raising a family are downstream of that deeper work. Marriages that last over decades tend to be the ones where both spouses have invested in the slow construction of a meaningful “us.”

What is shared meaning in marriage?

Shared meaning is the level of a marriage where the two of you have built common rituals, shared goals, shared symbols, and a shared sense of what matters and why. John Gottman placed Shared Meaning at the top of his Sound Relationship House model because it is what holds a marriage together when feelings, circumstances, and seasons of life shift.

What is the 7 7 7 rule for marriage?

The 7 7 7 rule is a popular guideline for couples that suggests every seven days you go on a date, every seven weeks you take a weekend away together, and every seven months you take a longer trip. Clinically, the rule itself is less important than what it points at: marriages need regular, protected investment in connection. The rhythm matters more than the specific intervals.

Does having children give your marriage more meaning?

Research suggests yes, with a caveat. Day-to-day life satisfaction often drops while children are young, but long-term life-meaning is significantly higher for parents than for non-parents. Couples whose children have grown often score high on both. Children are one of the most powerful sources of shared meaning available to a marriage, but they do not on their own create a shared sense of purpose. The couple still has to build that themselves.

Can a marriage have purpose without shared faith?

Yes. Shared faith is one strong source of shared meaning, but it is not the only one. Couples can build shared purpose through values, mission, parenting, work, service, creative projects, or any deliberate alignment of what they want their lives together to mean. What matters clinically is that the meaning is genuinely shared, not held by one spouse and tolerated by the other.

The Bottom Line

The purpose of your marriage is not handed to you. It is built. The good news is that you do not have to build it all at once. You build it through how you tell your story, how you flex with each other, what you invest in together, and how you treat the marriage itself as a relationship worth pouring into.

If you and your spouse have lost a sense of why you are still together, that sense can be rebuilt. Most of the couples we see in our practice did not start out with a clear shared meaning. They built it, lost track of it, and are now learning to rebuild it on purpose.

If you would like clinical support working through this with your spouse, our team offers couples counseling grounded in attachment, shared meaning, and the kind of clinical work that holds up over the long term. You can also find a fuller framework in our complete guide to strengthening your marriage. We offer a free 20-minute consultation if you want to talk it through with one of our therapists first.
