Monologue from "The Jukebox Diner"

The speaker reminisces about a past relationship and how the person left without hesitation. They mention how, for a while, they hoped every person passing by their window was their ex-partner returning. However, they now realize that none of them were. Despite this, the speaker still thinks about their ex-partner every day and remembers their perfect first dance together. They express confusion and regret, wondering what went wrong and what they did to cause the breakup. He would leave me without thinking twice, just like your daddy. For years after he left, men would walk past the window, and for a split second, I would think it was your father coming home, finally. But now they're just people. Every person in the world has walked by that window, and not one has been your father. And still not a day goes by that I don't think about him, and how perfect our first dance was. I was the snow queen, and I had my whole life in front of me, dream upon dream, and every dream started with him, with us building a life together. It was a cold December night, and the gym had been decorated like a sky full of snowflakes, and I was the snow queen, the most popular girl at the dance, with the most amazing man, the man I wanted to spend the rest of my life with. What happened? What did I do?
