I made the mistake of dating a coworker, and it’s been a complete nightmare. I’m 26F, and I briefly dated a guy, 27M, from my team for about a month. No commitment, just a casual fling. But now, it’s blown up in my face, and it’s ruined everything—including our tight-knit friend group of four. This guy? An absolute disaster to date, but somehow, he’s fine as a friend. Not to sound arrogant, but I’m way out of his league. Yet, I somehow let him worm his way into my life. He was obsessed with me at first, but then things took a turn for the worse. His hot-and-cold behavior is driving me insane, and I can’t believe I ever cared about him. He’s nothing like the person I want to be with. He’s not my type at all—he’s a total chauvinist. He even made me cry in bed with his cruel words when I was at my most vulnerable. How can someone be so heartless? The worst part? Even after all this, I can’t shake the attachment I feel. Maybe it’s because he was the closest friend I had at work, or maybe it’s just that we spent so much time together. But now, I’m stuck seeing him every day, and it’s messing with my head. Guys, please, talk some sense into me. My heart and mind are at war, and I don’t know how to break free from this toxic mess.
