I dated a co-worker for about 6 months. She was super nice, but after a while I just didn't feel like she was "the one". So, I broke up with her. We typically had opposite shifts but every once in a while we bumped into each other and she would shut down from her normally bubbly disposition into this mournful state. I hated that I did that to her but I couldn't just quit my job.

About two months later, she passed away from diabetes related complications at 23.

Before that point, seeing her at work was the hardest part of the job. But after, I would turn around and look to where she would sit, being reminded that not only did I break this poor girl's heart, but I'm never going have the chance to redeem myself in her eyes.
