Alan Fruzzetti's book The High-Conflict Couple: A Dialectical Behavior Therapy Guide to Finding Peace, Intimacy & Validation is very good (and very challenging) and he never mentions BPD.
Unfortunately the cover of my copy advertises Marsha Linehan, who wrote the Foreward, as the author of several books on BPD. . . Someone should tell the publisher to remove all references to BPD from the cover and author note!
I was hoping to suggest working through the book together with my uBPD husband but ended up reading it alone.
I have the audiobook version... but just a thought, I wonder if the paperback and hard cover have different covers that might not mention Marsha Linehan?
