Because on-again/off-again (on-off) relationships typically maintain their relationships in some form even after relational dissolution, a communication process that may be particularly relevant to understanding these relationships is relational maintenance. Using cross-sectional data, the current study assessed relational maintenance, uncertainty, and commitment to further understand how on-off relationships differ from relationships that do not have a history of renewals (i.e., noncyclical relationships). The sample of 487 participants completed a survey on either their current dating relationship or a postdissolution relationship. As predicted, on-off partners used less maintenance behaviors than noncyclical partners in current relationships, but, contrary to predictions, on-off partners did not use more maintenance behaviors in their postdissolution relationships than partners without a history of renewing. Path models assessing the interrelationships among maintenance, relationship uncertainty, and commitment also suggest relational maintenance operates somewhat differently in on-off and noncyclical relationships. Implications for on-off as well as dating relationships in general are discussed.
