In this book, Waehler describes bachelors' internal processes and interpersonal styles along a continuum with three specific bachelor types: Flexible, Entrenched, and Conflicted.

Bachelors is the first and the only book to examine the inner workings of the bachelor mind. Waehler explores the psychology of never-married men and their choices, looking at similarities as well as differences. He looks at their conscious and unconscious psychological profiles, the experience within their families of origin, their relationships with women, their development through adulthood, and their beliefs about marriage.

In the end, Waehler establishes patterns that lead to men maintaining their single status with varying degrees of satisfaction. He also provides practical advice on how to come to terms with various bachelor styles, or alternatively, how to successfully move from bachelorhood to marriage. Real life case studies are provided throughout, making this a book for the interested adult as well as researchers and other professionals.
