Self-Differentiation, Part One

Belonging Without Losing Yourself

Stop looking for the villain and start studying the dance. In a relationship, the pattern between two people may tell us more than either person alone.

Marriage has a remarkable ability to turn otherwise competent adults into much younger versions of themselves.

You can manage employees, negotiate contracts, make complicated financial decisions, and navigate most of adult life with reasonable competence. Then your spouse says, “You always do that,” in exactly the wrong tone of voice, and suddenly some considerably younger version of you has taken over the conversation.

Family systems therapists are not particularly surprised by this.

One of the major influences on how I understand couples has been Bowen family systems theory. Murray Bowen gave us a way of thinking about relationships that I have found useful throughout my years as a marriage and family therapist. Ronald Richardson later made many of Bowen’s ideas especially accessible for couples: instead of beginning with the question, How do I get my spouse to change?, begin with the considerably more difficult question, How do I become more responsible for myself while remaining connected to this person I love? That changes the work.

Each person enters marriage carrying an emotional history already in progress. We bring expectations about closeness, conflict, sex, money, affection, responsibility, anger, loyalty, religion, vulnerability, and what love is supposed to look like. Much of this was learned long before we knew we were learning anything. In fact, it’s passed down through generations.

We also learned ways of managing anxiety. One person learned to pursue when something felt wrong. Another learned to withdraw. Someone became good at keeping the peace. Someone else learned to argue until the problem was settled. One learned that anger gets attention; another learned that anger is dangerous. One wants to talk about the problem immediately. The other needs time to think.

Then these two people fall in love. At first, many of their differences are charming. Later, remarkably, some of those same qualities become the subjects of marital counseling.

Bowen called one of the central tasks of emotional maturity differentiation of self. The term sounds considerably more clinical than the idea itself. At its heart, differentiation asks a deeply human question: Can I become more fully myself while remaining meaningfully connected to you?

That sounds simple until someone you love is disappointed in you.

Can I know what I think without requiring you to agree with me? Can I listen to what you think without immediately preparing my defense? Can I love you without assuming responsibility for every feeling you have? Can you be unhappy with a decision I make without my having to change the decision—or withdraw from you—to make the discomfort disappear? Can we disagree without treating disagreement as rejection?

This is the difficult territory between belonging and becoming. Marriage creates an us, but a healthy us still contains two people. Intimacy does not require either person to disappear.

Differentiation is sometimes confused with independence. It is almost the opposite. Anyone can hold onto a position by leaving the room, refusing to talk, or deciding they no longer care what the other person thinks. Emotional distance can look impressively strong. Sometimes it is simply anxiety with better posture.

If the only way I can remain myself around you is to stay away from you, I may not be quite as free as I imagine.

Differentiation means remaining connected while holding onto yourself. Richardson’s approach to Bowen theory is particularly useful here because it keeps returning the focus to the one person in the relationship over whom I have any meaningful control: me. That can be irritating news when I have arrived at therapy with a carefully prepared explanation of what is wrong with my spouse.

Couples frequently arrive with two competing diagnoses of the marriage. Each person can describe, often with considerable supporting evidence, what the other person does that creates the problem. If only she would stop doing this. If only he would start doing that. Each is waiting for movement from the other before changing their own position.

Unfortunately, marriages can remain stuck there for years.

Bowenian work asks something different. What happens to me when the relationship becomes anxious? What do I predictably do? Do I pursue, criticize, explain, appease, fix, withdraw, become sarcastic, go silent, or insist that we resolve the matter before either of us sleeps again?

And what would it look like for me to function a little differently?

Anxiety is important because couples transmit it remarkably well. One person becomes worried and the other becomes worried about the first person’s worry. One presses for reassurance, which makes the other feel crowded. The second person pulls away, which increases the first person’s anxiety, which produces more pursuit, which produces more distance. Before long both people are doing precisely the thing that guarantees more of what they do not want.

This is one reason Bowenian therapy pays so much attention to patterns rather than villains. In many distressed marriages, there is no villain. There is a dance. Of course, each dancer is convinced the other person started it.

Some spouses overfunction. They remind, organize, anticipate, manage, correct, and solve. The more they do, the less the other person may do. Then the overfunctioning partner becomes resentful because everything depends on them, while the underfunctioning partner feels increasingly criticized or incompetent. Each person’s response quietly invites more of the other person’s response.

Other couples develop a pursue-distance pattern. The more one wants closeness, conversation, reassurance, or resolution, the more the other feels pressure and backs away. The withdrawal increases the pursuer’s anxiety, so the pursuit intensifies. Both people eventually conclude that their spouse is the problem. The pursuer thinks, If you would stop withdrawing, I wouldn’t have to chase you. The distancer thinks, If you would stop chasing me, I wouldn’t have to withdraw.

Both are correct enough to remain stuck. But differentiation interrupts the dance because one person begins paying attention to their own steps. That may mean learning to state a position clearly without forcing it on the other person. Bowen sometimes described this in terms of an “I-position.” Instead of “You never listen to me,” I might say, “This matters to me, and I want us to be able to talk about it.” An I-position does not guarantee agreement. That is precisely the point. It allows me to be clear about myself without making your agreement the price of my stability.

Marriage may be one of the great laboratories for differentiation because two people are attempting something inherently difficult: becoming one without becoming the same. There will be differences in temperament, money, sex, religion, household responsibilities, families of origin, recreation, neatness, punctuality, thermostats, and the correct way to do things.

Many couples deal with this by trying to eliminate difference. But that is counterproductive. Even if we could eliminate every disagreement, we might eventually discover that we had also eliminated one of the people. Marriage works considerably better with two.

The task is learning how to remain yourself while making room for someone who is equally determined to remain themselves. I can tell you what I think without turning my opinion into a demand. I can understand your position without pretending it is mine. I can allow you to have feelings about me without immediately trying to manage those feelings.

This does not mean that every marital problem is simply a matter of accepting differences. Couples make commitments to one another. Our choices affect our spouses. Betrayal, deception, contempt, coercion, addiction, violence, and chronic irresponsibility cannot be explained away as differences in personality. Differentiation includes having boundaries and taking clear positions about what we will participate in.

But most marriages also contain a great deal of ordinary difference, and ordinary difference can generate extraordinary anxiety.

This is where our earlier relationships still matter. We do not leave our families of origin behind when we marry. We carry parts of them with us. The person who learned that conflict threatens the relationship may experience a spouse’s disagreement as something much larger than disagreement. Someone who learned to keep everyone happy may find a spouse’s disappointment almost intolerable. A person raised around unpredictable anger may become extraordinarily sensitive to a change in tone. Someone from a family where vulnerability was dangerous may have learned to need very little from anyone.

Those adaptations once made sense, but when you get married this changes because both of you are exploring whether the old strategy still fits. Differentiation means becoming curious about these life-learned reactions rather than simply obeying them. I can notice that my spouse’s silence makes me anxious without immediately filling the silence. I can notice that criticism makes me want to defend myself without mounting the defense. I can recognize the urge to fix my spouse’s distress without assuming that distress is mine to fix.

That little bit of space matters.

Richardson’s practical use of Bowen theory also reminds us that marriage improves when we become less preoccupied with changing the other person. This is not because the other person never needs to change. They almost certainly do. So do we. The problem is that focusing relentlessly on our spouse’s functioning can become a very effective way of avoiding our own. Coming back to “I” redirects the point of focus. Instead of concentrating on what you are doing wrong, I become curious about what is happening in me. I have considerably more room to grow when I ask, What is mine here?Am I simply responding to what is happening between us, or is something older being stirred up—some familiar way I learned long ago to deal with distress?

The intensity and form of that reaction may be shaped by an old emotional pattern. In fact, that is the more interesting point: you really did say something that upset me, but why does this particular thing have so much power over me? So becoming curious isn't a curiosity about your partner’s response that may have triggered you, but being more curious about your own reaction to them.

What am I contributing to this pattern? What happens inside me when my spouse disagrees, withdraws, becomes emotional, or wants something I do not want? What am I trying to make my spouse do so that I can feel less anxious? What would it look like to respond from my values rather than from the pressure of the moment?

None of this happens perfectly.

Differentiation is not an achievement we eventually complete. Nobody wakes up one morning fully differentiated and receives a certificate. Whatever maturity we possess on Tuesday morning may become considerably harder to locate by Friday evening when we are tired, worried about money, and discussing something we have already discussed fourteen times.

Under enough pressure, all of us have familiar roads.

The work is noticing sooner.

I am becoming anxious. I am trying to make you agree with me so I can settle down. I am withdrawing because staying present feels uncomfortable. I am taking responsibility for a feeling that belongs to you. I am asking you to change something in yourself that I may need to address in myself.

That moment of recognition creates room for another choice.

Perhaps this is why differentiation has remained so useful to me. It is more than a marriage therapy technique. It describes something marriage continually asks of us: to become a person capable of both intimacy and integrity.

We do not become ourselves alone. Marriage shapes us precisely because another person gets close enough to challenge the ways we have learned to protect ourselves. Our spouses know where we are tender. They know our habits, contradictions, defenses, strengths, and several stories we wish they would stop telling at dinner.

That much closeness will occasionally create anxiety.

It can also create growth.

The goal is not to become so emotionally self-sufficient that our spouse can no longer affect us. That would be a strange definition of intimacy. The person we love should matter to us. Their happiness matters. Their pain matters. Their opinion matters.

It simply does not have to determine who we are.

A differentiated marriage leaves room for two people who can love deeply without controlling, disagree without abandoning, listen without surrendering themselves, and remain present when difference makes the room uncomfortable.

Perhaps that is one of the better descriptions of mature love:

I can be me. You can be you. And we can keep learning how to be us.
