Why You Can't Think Your Way Out of a Relationship That Hurt You

When we form an attachment to someone, the nervous system stores that attachment as a physiological reality, not just a memory or a thought. The bond you formed, even with someone who hurt you, lives in your body. It shows up as a pull in your chest when you hear a certain song, a jolt of recognition when you smell something familiar, a grief that arrives without warning years later in the middle of an ordinary Tuesday. This is not weakness. It is how attachment works. The nervous system does not distinguish between a bond that was good for you and one that was not, and it records both with equal fidelity.
