Differentiation: A Step Beyond Codependency

Not too many years ago, the buzzword in therapy was codependency. People who found themselves deeply embedded in the life of another were told they were codependent.

Codependency was often described as the addiction of control, as in a deep, abiding need to control, fix, or change the behavior and thinking of other people. In the mid-1980s, working on one’s codependency issues was all the rage.

I was introduced to the codependency movement in the early 1990s when the therapy world was being inundated with books, tapes, and conferences about freeing oneself from the prison of codependent living. The main idea is to learn to stop focusing on the life of the other person and begin focusing on your own life.

The recovery movement has a similar concept. It is conceptualized in the simplicity of the Serenity Prayer.

Accepting What I Cannot Change

God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. 

Anyone who has ever been to a 12-step meeting can most likely enunciate the well-used and often referenced adage about people, places, and things.

What can I change? Me, my thoughts, my choices, my actions.

What things can’t I change? People, places, and things.

Serenity, it seems, is wrapped up in the idea that…

“I need to concentrate not so much on what needs to be changed in the world as on what needs to be changed in me and in my attitudes” (Alcoholics Anonymous, 1976, p. 449.

Minding Myself Instead of Others

No matter how you frame it, the idea of “minding one’s own business” is as old as the human condition. People just seem to have an innate need or desire to get up in each other’s business. Which makes a certain amount of sense because it is usually more fun to run someone else’s life instead of tending to one’s own.

As I began to work on developing a less codependent way of being with others and an openness for acceptance and surrender, I often found myself struggling with how often I found myself drifting into territory that clearly was out of my control and was the responsibility of the other person.

Oh, I understood, or at least I thought I did, the premise behind codependency and working on my stuff instead of everybody else’s. But somehow, the whole thing remained a little bit of a mystery to me. I got better at setting boundaries. I learned to keep my side of the street clean. I tried really hard not to covertly try to change somebody to fit my agenda. But I had to admit. I wasn’t all that good at it.

That’s when my moment of clarity hid me. And it came wrapped up in a concept that, at first glance, didn’t seem to make a lot of sense.

Differentiation

– The ability to maintain one’s individuality or “self” while being closely or thoroughly engaged with another person.

In other words, the ability to be a team player and an individual all at the same time. Both a Me and a We. Wow! What a concept.

When I first heard the term, I thought it was just a new twist on the codependency premise. But as I began to learn and read more about differentiation, I realized that differentiation wasn’t just another concept.

Differentiation is a Principle that has Life-altering Potential!

Without sounding too dramatic, it would be correct to say that differentiation is the heart and soul of relational health and well-being.

Learning how to maintain one’s sense of self and individuality while being intimately connected to another may seem like a contradictory concept. But trust me, the ability to maintain one’s individuality within the context of relational connectedness is the key to intrapersonal and interpersonal contentment.

As much as human beings long for connection and togetherness, we also find it uncomfortable and frightening when we are pressured to give up parts of our autonomy or self to maintain a relationship.

No Wonder Relationships Feel Complicated.

  Like Dr. Dolittle’s fictional character, the Pushmi-Pullyu (push-me-pull-you), human beings struggle with the relational insanity that results from being simultaneously engrossed in and repelled by those we love.

Differentiation, however, frees us from the anxiety that forms as a result of these two conflictual needs and allows us to experience the wonder and joy of intimate, supportive Otherness while retaining our sense of individuality and autonomy.

In a state of differentiation, couples complement each other as opposed to completing each other. In a state of differentiation, we can be incredibly intimate without fear of losing our Self in the process.

It is, quite frankly, an amazing concept.

Learning to be a more fully differentiated person does not have to be a scary or confusing process.  The process of becoming a more fully functional and integrated self while remaining intimately connected with others can be an exciting and rewarding journey.

It is also a journey that you can begin anytime you are ready.

Want to know more about developing a more differentiated way of being with God, with yourself, and others? Perfect! Let’s get started today.
