I first came across this book while I was with a woman I respect so much. I wrote about her in Delay does not mean denial (by the way I think that is a MUST REad). I was impressed that a 59 year old woman was still studying how to improve on herself and her marriage.
This book teaches a whole lot. Helps husbands and wives understand their roles in marriage, the variation in their expectations, and what makes those expectations so different. That every family needs a leader. Consequently, wives may unavoidably take on responsibilities they'd rather not bear. The result? Resentment, and an emotional distancing that can sabotage an entire family system.
