What is the author's style in After the Affair by Janis Abrahms Spring?

Although the text does not directly advise against having an affair, it does illustrate the profoundly damaging aspects of affairs and notes the lengthy and often difficult process of recovering from an affair—both for the hurt partner but also for the unfaithful partner. The text's principle function, therefore, is not to prevent affairs but rather to offer tools to those who, having experienced an affair in some way, desire to rebuild their relationship. The text offers advice and tools to both the hurt partner and the unfaithful partner with the realization that rebuilding a damaged relationship takes the total future commitment of two individuals.
