Both patterns can create distance when closeness, dependence, conflict, or emotional demand rises. Over text, that may look like shorter replies, longer gaps, practical language, avoided questions, or a request for space.
The overlap is why one silence cannot identify the style. People also become quiet because of work, low interest, depression, conflict, habit, or a wish to end the relationship. Attachment becomes a useful hypothesis only when the behavior repeats across similar moments and changes with closeness, reassurance, or pressure.
The difference is dimensional. Fearful avoidance usually combines substantial attachment anxiety with avoidance. Dismissive avoidance is more strongly marked by avoidance and self-reliance, with less visible anxiety about losing the bond. Those are tendencies, not fixed scripts.
