In response to partner phubbing, participants higher in attachment anxiety reported more resentment, curiosity, and retaliation in response to phubbing. When retaliating to phubbing, those higher in attachment anxiety did so to seek support and approval from others, whereas those higher in attachment avoidance did so to gain approval from others.\n\n\nConclusions\nOur findings contribute to the understanding of how adult attachment patterns influence people's responses to partners' phubbing and well‐being.\n\n"]
