My wife, Marina, started going to a fitness gym after I casually asked if she had gained weight. After joining, her body gradually became toned, and I felt reassured—too reassured. But things began to change: she started wearing flashy lingerie, and there were days when she wouldn't answer her phone. I sensed something was off, yet I couldn't bring myself to confront her. Unbeknownst to me, Marina had grown increasingly close to her handsome personal trainer, crossing the line and indulging in secret, sweaty encounters behind my back.
