Here is my letter to the editor of Psychology Today, in response to a recent article entitled, “A Natural History of Female Infidelity”.

In my many years as a couple therapist, I have observed that men and women cheat for different reasons. While no hypothesis is ever 100%, there seems to be a definite pattern to the difference between female and male infidelity; and it’s not just about sex for either of them . A woman tends to be sexually receptive to another man when her bedrock need for emotional sustenance is not being met in the relationship with her mate. A man seeks the comfort of other women for other reasons.
