The purpose of this study is to investigate the effect of romantic relationship on individuals’behavior toward their friends as well as the importance of friendship in such process. As behavioral indexes, the frequency and duration of behavior (e.g.,texting) and distribution of resources (e.g.,affection, status) toward person in close relationships were employed. One hundred and thirty five undergraduates who have romantic partners completed the questionnaires about their partners and same-sex friends (i.e.,closest friend, second closest friend). The results showed that perceived attachment function of their romantic partners was negatively correlated with, how often they would call and how much they would invest affection toward their friends. This tendency was more apparent toward second closest friends. And, those who perceived attachment function of their romantic partners to be relatively low and rated their friendships to be important were more likely call and text their friends. This interaction effect was found only with closest friends. Attachment function of romantic partner was discussed in relation to individuals' behavior toward their friends.
