“…Fluctuating levels of relationship quality are associated with decreased commitment and eventual breakup in dating couples (e.g., Arriaga, 2001); more destructive conflict between dating partners and more relationship problems in cohabiting couples (Campbell, Simpson, Boldry, & Rubin, 2010); and increasing psychological distress, decreasing life satisfaction, and depressive symptoms over time in dating and cohabitating relationships (Whitton, Rhoades, & Whisman, 2014;Whitton & Whisman, 2010). Similarly, greater variability in perceptions of partner commitment is associated with eventual breakup as well (Arriaga, Reed, Goodfriend, & Agnew, 2006). Thus, couples with higher variability in relational constructs are prone to negative outcomes.…”
