There are not many differences between relationships involving two committed women and heterosexual relationships. Lesbian couples are likely to report the same level of satisfaction as heterosexual couples, as well as similar patterns of relationship quality over time. Two women in a committed relationship may even argue about the same things as heterosexual couples.

Committed relationships between two women defy common stereotypes about same-sex relationships. Lesbian relationships are often loving, durable and stable, in contrast to stereotypes which state that relationships between two women are less stable. Research in the November 2004 issue of the "Journal of Marriage and Family" indicates that two women in a committed relationship are not maladjusted and do not have innate traits that lead to issues within a relationship. On the contrary, these relationships are just as safe and secure as heterosexual relationships.

When women are committed to each other, they are more likely to handle conflict positively. According to 2005 research in "Current Directions in Psychological Science," lesbian couples more often argue efficiently, avoid patterns of demanding and withdrawing in conflict, and are more likely to compromise and find solutions. This distinct difference in relationships between two committed women may be due to a more equal power structure between the couple, as well as a strong value of equality.

Lesbian couples are more likely to share chores compared to heterosexual couples. Two women who are committed to each other share household tasks in numerous ways. They are not bound by gender roles, are more likely to balance chores, and do chores based on skill. Each of these factors contributes to committed women sharing the burden of household work.
