Divorce Remedy even warns you that once any addictive/obsessive behavior has started the person acting on that behavior must suffer some major loses before they start to turn their life around.
I can speak from experience on that one. I was the cheater in my home and my husband did 180s left and right and I never even noticed them.
Once he started packing, calling lawyers, and began to inconvenience me was when I started to reconsider my behavior.
