Because the behavior people remember is the disappearance.
One partner asks what changed. The other goes quiet. The silence lasts long enough for uncertainty to become humiliation, then the story gets told online from the side that still has words. That story often has a real wound inside it. Being left in ambiguity hurts. Plans that evaporate, affection followed by distance, and conflicts that never get repaired can make a person question the whole relationship.
The mistake happens when the behavior becomes a character verdict. “They withdrew when closeness rose” turns into “avoidants use people.” “They could not stay in the conversation” turns into “avoidants have no empathy.” A painful pattern gets converted into a type of human being.
Online content makes that conversion easy because attachment labels offer closure. If the person was “an avoidant,” the confusing ending receives a cause, a predictable script, and a community that recognizes it. The label can help someone name what happened. It becomes less useful when it claims to explain every motive and future action.
