Is Infidelity Inevitable? (Part II)
Part 2: The Limits of Self and System
This is part two of a three-part series. Part one established the question and reframed infidelity as the absence of fidelity to your own wholeness. This part examines two limits on our autonomy: the internal one, where we collapse ourselves into labels we don’t actually resemble, and the structural one, where we pretend the systems holding our lives together don’t shape the choices we make inside them. Part three turns to discernment, communication, and the honest position underneath all of it.
When a client first sits across from me and refers to themselves as a cheater, I stop them and ask them to tell me what a cheater is.
What follows is almost always the same. They describe a character. Someone calculating, callous, fundamentally selfish. Someone who lies easily, takes pleasure in deception, has no real love for the person they’ve hurt. The character is vivid. Cinematic, even. And the character is never the person sitting in front of me.
The person sitting in front of me is usually devastated. Often confused about how they ended up here. Often grieving versions of themselves they didn’t realize they had abandoned years ago. They are looking at themselves from one angle — the angle the culture handed them — and mistaking that single view for the whole picture.
The label feels like accountability. It’s the opposite. It’s a way to stop looking.
This is what I mean when I say we have almost no understanding of power, control, or autonomy. We think we are exercising agency when we name ourselves harshly. We think the verdict is the work. But a verdict is the end of inquiry, not the beginning of it. The moment you collapse yourself into cheater, you have handed your autonomy over to a script you didn’t write, and you have called that handover responsibility.
It isn’t. It’s a more sophisticated form of avoidance. Self-flagellation performs remorse without producing it, because remorse requires staying in contact with the actual texture of what you did and who you were when you did it — neither of which fits inside a one-word character.
And then there is everything outside the room.
The cheater-character is one limitation on autonomy — the internal one. The other limitation is the system the person is embedded in, which we almost never talk about honestly when we talk about infidelity.
A marriage is rarely just a marriage. It is often a health insurance plan. A custody arrangement that hasn’t been written down. A visa. A mortgage that requires two incomes. A parent’s stability — sometimes literal stability, sometimes the kind that keeps a person from drinking themselves to death — that runs through the relationship’s existence. A child whose entire developmental scaffolding assumes both adults stay in the house. A family member whose job depends on the in-law connection. A community whose shape depends on the couple’s continuation.
These are not romantic considerations. They are structural ones. And they don’t disappear because someone has discovered they are no longer in love, or that they were never in love, or that they have changed in ways that make the original arrangement unworkable. The interdependencies stay. The bills stay. The insurance card stays. The kid still needs to be picked up from school.
When we talk about infidelity as if it is purely a question of personal character, we are pretending these constraints don’t exist. We are imagining a frictionless adult with no dependents and no obligations and no health conditions and no immigration status, choosing freely between integrity and betrayal. That person is rarely the person actually making the choice.
This doesn’t excuse deception. It does explain why the human in front of me, looking at the wreckage of their own behavior, is usually not a moral failure but a person who could not find a way to honor every commitment they were already inside, and made the worst-available compromise rather than what they would have made under different conditions. That is a different conversation than cheater versus faithful. It is the conversation we should actually be having.
There is one more limitation here, and it’s the most ordinary one. Being in relationship with a specific person, for a considerable length of time, is itself a constraint on what either of you can know in advance. You cannot promise fidelity to a future version of someone you haven’t met yet. You cannot know what twenty years with this particular nervous system, this particular grief, this particular evolution will ask of you. You signed up for an idea of a person. Time produces the actual one. The gap between those two is where most of what we call infidelity actually lives.
Two limits, then. The internal one, where we hand our autonomy to a label that flattens us. The external one, where we pretend the system we’re embedded in is incidental rather than determinative. Both invisible to the person inside them. Both load-bearing in how the choice actually gets made.
Part three is what to do with all of this — without abandoning discernment, and without pretending the limits aren’t real.
Thank you for saying so clearly what most of us have been thinking for years. It’s sad that this conversation is constantly shut down by judgmental pearl clutchers.
