He Was The Sun (And They Were All Planets)
She always knew how every girl in the Seam and in the Town would swoon over his tall frame, steely gray eyes and olive colored skin. She could see it too, she just didn't find it quite as attractive as all the others did. She knew it was supposed to be attractive, but she just didn't find it as attractive as it was supposed to be. Maybe all the other girls were just idiots.
Then she met Peeta. Sweet, innocent Peeta who did things as cheesy as the bread he baked to make her happy. Or at least, try to make her happy. She always was out of orbit with everyone else in District 12, but now she was out of orbit with someone else. It felt nice, carefree even like love. For a while, at least. Then she slowly began drifting away.
Peeta was like a moon that revolved around her. Not many people cared all that much about him. She was his planet, something he couldn't live without. To her, he was just a moon. She could live without him, with him, it didn't matter all that much so she decided not to break it off with him.
Slowly, and surely, she began drifting in line with all the other planets. She began to revolve around Gale, who seemed to be the center of attention, the center of the town, the beating heart in a human, the sun of the entire solar system. It was called the solar system for a reason, it was the sun's world. Not the planets'.
She didn't notice it as first. They had always been friends, but now, instead of two separate solar systems, it seemed that hers' had merged with his and she had gone from being his sun to his planet. It didn't make much sense in her mind. He was the sun, she should've seen it coming. It's only so long before one begins to revolve around the sun.
How she wished Peeta could've been the sun instead. Sweet, adorable Peeta who loved her very much; he loved her too much for his own good. She could never break it off with Peeta, he was much too fragile and she didn't want to hurt him. She'd have to learn to love the moon and detest the sun.
It didn't help much that Gale was still the center of the entire district. Every conversation she had with anyone at all eventually led to Gale. She couldn't ignore him even if she wanted to, he was a bright shining ball of nuclear that everyone except her was intent on always orbiting around. She wanted to escape the deadly cycle, stop orbiting around him.
"Delly?" Peeta asked quietly, looking at her with the oddest look in his eyes. Maybe he already knew, she thought feverishly, her face turning as red as tomatoes. She turned towards him, brushing her blonde hair out of her face. It was the exact same shade as all the town's peoples'. Like Peeta.
"Um, yeah?" she managed to squeak out, absentmindedly braiding her hair.
"You're braiding your hair. You only do that when you're nervous," Peeta noticed, giving her an odd look. She immediately stopped braiding her hair. She didn't even know she did that when she was nervous. Of course, Peeta would be the one to notice every little thing.
"Oh, it's just the, um, test, um, later today," she lied, beginning to braid her hair again, this time faster. Her hair fizzled up, the static from her hands making it frizzle in a messy curl. She would've laughed if she wasn't so nervous.

She was so relieved when Peeta announced his love for Katniss on the big screen. She really should've seen it coming; she was the distraction from Katniss, the overcorrection. Just in the same way he was the overcorrection for Gale. She still hadn't managed to stop revolving around him, because planets never stop revolving around the sun.

She was there when they had kissed. She'd felt a bitter twinge of jealousy towards Katniss, who managed to take all the men in her life. She knew she shouldn't blame Katniss for it. After all, he was still the sun.
He was the sun and they were all planets.
So, I imagine Delly dated Peeta before Peeta dated Katniss. Makes sense. The whole Gale part was the whole "everyone loved him" thing.
