Cohabitating middle-aged men seem to feel more depressed than married men because they

A) worry about not having care in their elderly years from their mate.
B) cannot determine the quality of the relationship.
C) still feel divorced or single.
D) None of these

Cohabitating middle-aged men may still feel like they are divorced or single, which can lead to feelings of depression. This is because they may not have the social or legal recognition that comes with being married, which can affect their sense of identity and self-worth. Worries about not having a care partner in their elderly years or the quality of the relationship may also contribute to feelings of depression, but it is likely that feeling divorced or single is the primary factor.
