This study examined the frequency of fusion in lesbian and heterosexual women's relationships and the relationship of fusion to other relational variables. The study found that there were no differences between lesbian and heterosexual women's levels of fusion and that fusion was strongly related to both satisfaction and dependence.two women together is a work nothing in civilization has made simple (Rich, 1978, p. 35) In the growing body of literature on the nature of conflict in lesbian relationships, researchers have often focused on the balance of power between female partners.

Fusion is frequently identified as a source of conflict in lesbian couples, yet articles on fusion often Downloaded from fail to define the word conflict or to investigate the possibility that it encompasses behaviors other than normal healthy arguing.This article explores the role of fusion in women's relationships. First, it reviews the affect of socialization on lesbian relationships. Then it presents not only the authors' study of the frequency of reported fusion among lesbians and heterosexual women, but also it illustrates other relational characteristics that are related to fusion.
