I stumbled upon this great talk last year by Pamela Meyer who wrote the book "Liespotting". Being a lie spotter is a skill. Many times I am asked about how to go on after a pathological love relationship. There is not one short answer but having the skill of spotting a lie is a good place to start. It is important to look for a pattern of behavior...that takes time. So, while you may be engaging in a new relationship or evaluating the state of a current relationship take some time to develop the skill of lie spotting.
