When I divorced my husband of 12 years, I was so depressed. My friend Ava took me in. She saved my life. 8 years later, I ran into my ex. The first thing he asked: “Are you still friends with Ava?” I nodded. He smirked. He said, “So you still don’t know that she’s the one who ruined our marriage?” I froze when he revealed that the woman he’d had a brief affair with—the one that led to our divorce—was Ava. It turns out Ava had felt so guilty for destroying my marriage that she tried to make it up to me. She wanted to do something good, so she made sure I was okay and asked me to move into her house. My whole reality crumbled. Never in a million years would I have suspected that, behind my back, she was with my husband—while pretending to be the perfect friend. Now, I’ve lost my trust in everyone.
