What is the theme in After the Affair by Janis Abrahms Spring?

Reacting to the affair is the main theme. The psychological process of reacting to the affair opens the book and is one of the three dominant themes considered. In general, the text examines the reactions of only two of the three individuals involved in the affair—that of the hurt partner and that of the unfaithful partner. As the text assumes that the marital relationship will persist beyond the affair, logically the lover's reactions are not fully examined, as the lover is not a component of the rebuilding process.
