When betrayal comes from two directions, the damage is not just emotional-it is relational, social, and deeply personal.This book explores what happens when a partner's infidelity collides with family loyalty, and forgiveness is expected before safety is restored. It examines the pressure to keep the peace, the confusion between obligation and trust, and the quiet cost of being asked to move on for everyone else's comfort.Rather than telling you what choice to make, this book helps you understand why the situation feels so disorienting, why forgiveness is often rushed, and why distance can be protective without being cruel.Your Partner Cheated With Your Sibling is not about revenge or reconciliation. It is about clarity, boundaries, and reclaiming agency when family narratives threaten to override your own.The second book in the When Trust Is Broken series.
