So this was influenced by Grenade by Bruno Mars. It's not the best thing I've written lately, and I don't think it flows very well. It's kind of repetitive and scrambled. But yeah.
He had taken everything, all he was and all he'd ever had, and offered it to her. She could have had him, if she wanted. And he could have her. He would do anything, absolutely anything for her. He'd give up everything and take whatever pain that was sent his way. He would kill. He would die. And to some extent, she would too. Years ago, she would undoubtedly take a bullet for him, he knew it. Because he was all she had.
And then she gained Peeta.
Stupid, clueless Peeta, who had no right to her. Gale had claim to her. He knew her. He knew everything about the girl he loved, had explored every crack and crevice of her mind until he knew her better than he knew himself. Peeta watched from afar, pretending he knew anything about Katniss Everdeen. He saw the little schoolgirl with typical dark looks of the Seam, sullen, starved skin, and two braids resting on her shoulders instead of one down her back. And he fell in love with her. Before he even knew who she was, save for her name and whatever his father had told him, he fell in love with her.
It wasn't fair.
Of course, life wasn't fair. If it were, they'd have spent their lives in luxury, with plentiful food and heat every winter. If life were fair, she wouldn't have been sent into a fight to the death with rich, healthy brutes who could only dream of snapping her neck, of slitting her throat or piercing her chest. If life were fair, he would have her, and she would do anything for him as he would for her.
But life wasn't fair, so he watched as Peeta kissed her, Peeta kept her alive, Peeta listened to her sorrows and worries and made her whole again. How was it that Gale had given everything and didn't get her, while Peeta could waltz in with everything, keep what he had, and still have her?
Maybe Peeta was the reason that life wasn't fair. Maybe the annoyingly perfect merchant boy, who could take and take without giving anything back to karma was the sole reason that Gale's life sucked.
It didn't matter. He was home now, or as close to home as he'd ever be again. In the glorious District 2, previously one of the Capitol's lapdogs, with a wife that he didn't love and children that he did. And he would still give everything, or what pieces of everything he could scavenge out of his broken self, for Katniss. She'd never do the same. But that was okay.
