I, too, was in a marriage for over 25 years with a "sociopath next door." I have a psychology background. Yet I would never think my husband was a sociopath because he wasn't mass killing people like Ted Bundy. He had a very high position in government, where his command was done without question. He also has other mental issues, including extreme ADHD, porn/sex addiction, and hoarding. Yet there was a coldness about him which wasn't explained. In the last years of our marriage as he became more mentally erratic, I started to secretly closely watch all of his behavior. I was shocked by what I found. This was the man I was living with? What I found was a Dr. Jeykll/Mr. Hyde personality. When confronted with some of the stealing behavior, he coolly denied it without blinking an eye, even when presented with evidence. I knew then, this wasn't the first time he lied. He was a master at it. Still, I didn't peg him for a sociopath, even though he passed the online test with flying colors. After all, he didn't hit me. He did charitable things for others. (It helped his career.) It wasn't until I read this book (twice) that things finally sunk in. I'm sure if they did a brain test, they would find his brain doesn't fire like others. This book has helped the healing and understanding process, although it is still difficult to understand how a human being can act as the sociopaths do. I agree that all law enforcement and those in the courts should read this.
