Abstract
Commitment uncertainty represents an ongoing state of conflicted feelings or thoughts about the future of a relationship. It is currently an underexplored dynamic within romantic relationships and may be a key component of young adult relationships that may influence the likelihood of relationship termination. When commitment is uncertain, individuals may engage in serious monitoring of relationship alternatives. The authors examined the associations between commitment uncertainty, serious alternative monitoring, attachment style, and relationship termination. Results supported the hypothesis that higher levels of commitment uncertainty are related to greater likelihood of termination. Interestingly, serious monitoring of alternatives was not related to relationship termination. Implications are offered for the management of these important relational processes.
