Gottman has some terrific research evidence as a professional and do admire him. Though in this book, he denotes "Sex Addiction" as a potential issue. This is dated information and even the World Health Organization has ruled against this biased label. Yes, I am also a professional in the marriage counseling realm. This book has terrific insights for both lay-persons and professionals alike. Though one also needs to not further increase judgments regarding a banned biased "addiction" claim.
