This is a delicate topic that is often not handled delicately. Firstly, we are not taught how to create healthy, happy, mutually-beneficial relationships.
Then, when we encounter problems within that relationship, we don’t have the tools to resolve our differences for the greater good of all concerned. In some cases, when conflict cannot be resolved, the relationship either ends or one or both partners may seek solace with another person.
Affairs are commonplace today and lead to pain and devastation for all concerned, whether you are the one who cheated or the one who was cheated on.
There is always shame and guilt for the betrayer and hurt and humiliation for the betrayed. Perhaps if we have the deeper conversations and create our relationships consciously, rather than by default, we can actually prevent affairs from happening.
We live in a world where most people wear two faces: one for the public and another behind closed doors. Couples become isolated.
