The association between insecure (anxious and avoidant) attachment and dissolution of romantic relationships has been investigated in previous studies. The aim of this paper was to review literature examining the association between adult insecure attachments, reactions to, and coping with breakups. A literature search resulted in seven articles, from the period between 1992 and 2011, investigating insecure attachment and dissolution of romantic relationships. The present review showed that anxious attachment was associated with negative emotions, proximity-seeking and hostile behavior, appraise of the breakup as a threat, and a lack of ability to handle it, in addition to less adequate coping strategies. Avoidant attachment was associated with both positive and negative emotions, avoidant behavior, assessment of the breakup as a threat, positive assessment of the ability to handle the situation, and little use of social support as coping strategies. The association between avoidant attachment and reactions to, and coping with, breakups was affected by differing operationalization of attachment. The results are discussed in light of general attachment theory. On the basis of a theoretical similarity between insecure attachment and vulnerable narcissism the results are discussed in relation to vulnerable narcissism. The knowledge obtained from this review can have implications for clinical practice, and for further research regarding the association between vulnerable narcissism and romantic relationships dissolution.
