Surviving infidelity is a choice. You must decide if your marriage is based on solid foundations, or if the infidelity is a symptom of a larger problem. Infidelity is usually a sign that the person isn’t getting their needs met in a relationship, but that may or may not be the fault of a lackluster marriage. Oftentimes, an affair just represents the person’s need to feel desired by someone different – whether it be someone younger or older, from a different class or economic background, etc. That may be an indication of the person’s insecurity rather than a relationship problem itself.
