I found ‘Boundaries’ By Dr. Henry Cloud and John Townsend helpful

It does have religious content which I know some people might reject out of hand however the authors do a good job explaining how and when to set boundaries and its not preachy.

Actually it is often the religious or spiritual minded person that wishes to be loving and unselfish that are more likely to forget to set their own limits and limitations.
