Infidelity has been the only excuse needed to get out of a relationship. When we consider how often it occurs it becomes a very human thing; possibly not a sign of a failed relationship or a disastrous human being. We can look at what, if anything, was missing beforehand, what is lost afterward, and what happens during. For most people, the most painful part is the breach of trust. Properly treated, infidelity can become a revitalizing point in the relationship, or the exit point.
