The field of relationship research is currently witnessing an explosion of interest in romantic love. Several theories have been proposed to explain various features of love. This article summarizes some of these and argues that they can be integrated within an attachment-theoretical framework. In the course of the argument, love is conceptualized in terms of emotion theory and as a complex of behavioral systems, involving attachment, caregiving and sex. Although a great deal of research remains to be done, the attachment-theoretical approach to love already offers several advantages over rival approaches.
