Love You, Love You Not In a random sample of unmarried emerging adults (half men, half from two-parent homes, two-thirds European American, all from Toledo, Ohio) who had had a serious dating or cohabiting relationship in the past 2 years, some (15 percent) had broken up and not reunited, some (41 percent) had been together without breaking up, and some (44 percent) were churners, defined as having broken up and gotten together again with their partner. As you see, young adult relationships are often problematic, but churning correlates with the stormiest relationships, with half of churners fighting both physically and verbally.
