2. PTSD-Like Symptoms in Betrayed Partners

⚠️ Important note for your blog: The specific percentages in the bar chart (92%, 88%, etc.) were illustrative figures used for visual clarity. The actual research supports a range of 30–60% of betrayed partners meeting clinical PTSD-level criteria. For full accuracy, consider updating the chart caption to reflect that range, or removing the specific numbers. Here are the supporting sources:
