I’ve seen some version of that phrase in several different accounts of what an affair meant to the unfaithful partner, and the more I think about it, the more contradictory it seems.
How can a relationship with another person be "something just for me"?
By definition, it isn’t just yours. It is relational. It is dyadic. There is another person involved, another person whose attention matters, whose responses matter, whose availability matters, whose approval matters, and whose behavior can change how you feel.
Something truly "just for me" would seem more like developing an interest of your own, taking time alone, making independent choices, rediscovering preferences you had stopped expressing, building friendships, creating something, learning something, or developing a stronger sense of self that does not depend on another person.
An affair is almost the opposite of that.
Especially when the affair partner and the affair relationship are, in many obvious ways, worse than the primary relationship.
The AP may be less available. Less dependable. Less invested. Less caring. Less knowledgeable about the person. The relationship itself may have secrecy, uncertainty, inconsistency, very little shared reality, and very little evidence that it could survive ordinary life.
And yet sometimes that seems to make the attachment stronger rather than weaker.
There can be an intermittent-reward quality to it. The spouse may provide affection, admiration, security, attention, and validation consistently enough that it becomes expected and almost invisible. The AP provides much less, but because it is uncertain, every small reward becomes highly salient.
Will they text today?
Will they say something nice?
Do they still want me?
Will I get attention this time?
The scarcity itself starts making the reward feel more valuable.
And if that is what is happening, then I struggle with calling the affair "something just for me."
Because that is not really selfhood. That is still locating something essential in another person's response to you.
If anything, it seems deeply invalidating to the self.
You may tell yourself that you finally found something that belonged only to you, but then you become intensely dependent on maintaining the affair container. You need the messages. You need the attention. You need the validation. You need the fantasy. You may begin protecting the relationship, rearranging your life around it, pushing boundaries to preserve it, or experiencing withdrawal when access to it is threatened.
At that point, what exactly was "just for you"?
You have not become less relationally dependent. You may simply have moved the dependency somewhere else.
That becomes even more troubling to me when someone has spent years losing themselves in a primary relationship through masking, over-accommodation, poor differentiation, or an inability to openly express what they actually want.
If the problem was, "I lost myself in my spouse," then escaping into an affair and losing yourself in an AP does not look like reclaiming yourself.
It looks like repeating the same problem in a different relationship.
Real individuation would have been learning how to remain yourself while staying connected to another person. Saying what you actually want. Allowing disagreement. Establishing boundaries. Developing independent interests. Becoming capable of tolerating another person's disappointment without reshaping yourself around it.
That is "something for me."
An affair can feel private, secret, exciting, separate from ordinary life, and therefore personally owned. I understand why someone might experience that subjectively as "mine."
But I think there is an important difference between something being **secret from your spouse** and something actually being **for yourself**.
Those are not the same thing.
And if the affair becomes another place where your sense of worth, desirability, identity, or emotional stability depends on somebody else's intermittent attention, then describing it as self-discovery may obscure what actually happened.
Maybe you did not choose yourself.
Maybe you just chose a different person to disappear into.
