Me: BW, 40.......Him: FWH, 40
That's a little difficult since codependency happens within the context of a relationship. I can give three recommendations that do not specifically focus on romantic attachments, but all the books I know of at least touch on the subject since it is the primary intimate relationship in adults' lives.
Here are the books:
The Dance of Intimacy: A Woman's Guide to Courageous Acts of Change in Key Relationships by Harriet Lerner, PhD
Codependent No More by Melodie Beattie
Boundaries: When to Say Yes, How to Say No to Take Control of Your Life by Drs. Henry Cloud and John Townsend
Not all of these use the term "codependent" but they all get at the types of behaviors and thought patterns that characterize codependence.
