Caught in the Moment of Passion

I’ve always felt this weird tension with one of my co-workers. We’ll call him Mark. He’s been older than me, he’s 18+, but it feels like a lot more considering how experienced and mature he seems compared to the rest of us at work. It wasn’t until last month that our dynamic started shifting. I was working alone late one night, finishing up inventory when suddenly there was Mark in the back room. He walked over, leaned against the counter, and we talked about everything except what was really going on between us. I’ve always admired how he handles himself; every interaction with him leaves me feeling both flustered and drawn to him like a moth to a flame. Last week, after hours, I had no intention of flirting or anything beyond being professional as usual, but somehow it just happened. We ended up alone in the storeroom, and for a moment everything felt right. But then I realized what was happening. We’re at work! And we were about to do something that would probably get us both fired if anyone walked in on us. The thought hit me like a freight train, there’s no way this can continue. But when Mark looked over and smiled, I couldn’t say no again. I keep wondering what people would think of me if they knew. Would they see me as weak for giving into something so risky? Or just someone with poor judgment who needs to learn boundaries better? It’s like I’m caught in this weird limbo where I know what's right and yet can’t resist the pull towards Mark. I should probably say something or find a new job, but part of me is still drawn back every time I see him. I want to believe that it was just a momentary lapse of judgment, but my feelings have grown more entangled since then. Maybe this won't end well at all.
