Here are five books that can help you sail through the rough seas of a marital crisis.
Should I Stay or Should I Go by Lee Raffel M.S.W.
Lee Raffel may not deliver on the answer to the question posed by the title of her book but she does offer a path toward this answer. The path is what she terms "a controlled separation." This is contrasted with an emotional separation by having clear goals and boundaries.

Dr. Delis' book gives fine detail to the dynamics of relationships when one partner cares more than the other. He teaches about how to protect yourself from your feelings.
