Thinning
noun /THIN-ing/ — The slow, barely perceptible withdrawal of emotional presence from a relationship.
Definition
The slow, barely perceptible withdrawal of emotional presence from a relationship — when someone is still technically there but has begun to disappear in all the ways that matter. Thinning is the colour draining from something before anyone names it.
Beyond the definition
Thinning is insidious because it happens too slowly to point to. The texts are a little shorter. The questions about your day stop. The curiosity about your life dims. None of it is a single event. All of it is a pattern. And by the time it's undeniable, enough time has passed that the other person will say nothing changed.
Origin & history
Contemporary English gerund repurposing the physical process of gradual dilution for the emotional domain — the slow reduction of relational presence and investment.

Slow Disappearance of Presence
