Lesbians in Love: Why Some Relationships Endure and Others End.

Lesbians often begin romantic relationships with high hopes that their relationships will be satisfying and long-lasting. Why do some women maintain committed and stable relationships while others do not? This article considers factors that affect commitment and stability among lesbian couples. We begin by reviewing previous empirical research on the topic. Next, we test a leading model of commitment using survey data from 301 lesbian couples who participated in the American Couples Study (Blumstein & Schwartz, 1983). According to Caryl Rusbult's model (1983), an individual's commitment to a relationship is affected by three general factors: satisfaction, the quality of alternatives to the current relationship, and investments made in the relationship. In turn, a woman's degree of commitment influences relationship stability. Path analysis provided strong support for Rusbult's model. Nonetheless, this model did not fully explain the sources of commitment and stability in lesbian relationships. Consequently, we consider unique aspects of the social environment that may affect commitment and stability in lesbian relationships. [ABSTRACT FROM AUTHOR]
