I get why my answer feels unsatisfying. From the outside, it looks like someone must have been getting something meaningful out of the lie, otherwise why do it? And yes, there were moments that felt good in the moment. The ego strokes, the validation, the intensity. But those weren’t signs of happiness. They were hits, not fulfillment. They were reactions, not connection.
Survival from what?
The threat wasn’t external. It wasn’t my partner. It wasn’t consequences. It was my own internal world. I didn’t have the skills to regulate shame, fear, conflict, or discomfort. I didn’t have the ability to sit with myself honestly. So the "survival" was from facing who I actually was. The mask wasn’t protecting me from my partner. It was protecting me from myself.
That’s why compartmentalization feels so alien from the outside. You’re imagining someone consciously turning off their brain to enjoy the lie. But the truth is simpler and more disturbing, you don’t think about it because you don’t have the internal architecture to tolerate thinking about it. It’s not a calculated detachment. It’s an underdeveloped one.
