I partially thought of this myself, and when I read Don't Leave by IceFire9, it gave me the encouragement to write it. So visit it if you want to see this written better. It is K plus, with 744 words if you want to find it. Also, in this Ron isn't as accepting, and he fights for Harry not to go into the Forest.
He was feet away from her when he realized it was Ginny.
He stopped in his tracks. She was crouching over a girl who was whispering for her mother.
"It's all right," Ginny was saying. "It's okay. We're going to get you inside."
"But I want to go home," whispered the girl. "I don't want to fight anymore!"
"I know," said Ginny, and her voice broke. "It's going to be alright."
Ripples of cold undulated over Harry's skin. He wanted to shout out to the night, he wanted Ginny to know he was there, he wanted her to know where she was going. He wanted to be stopped, to be dragged back, to be sent home…
But he was home. Hogwarts was the first and best home he had known. He and Voldemort and Snape, the abandoned boys, had all found home here…
Ginny was kneeling beside the injured girl now, holding her hand. With a huge effort Harry forced himself on. He thought he saw Ginny look around as he passed, and wondered whether she had sensed someone nearby. But it was confirmed when she got out her wand, and pointing it directly at him, said, "Stupefy."
It was at this moment that Harry regretted telling her about the Cloak, and he knew that though he could not die while under the Cloak (as Death could not find him), he could most likely be stunned or injured. So it was with great effort that he pulled out his wand with the speed of a bullet and said softly, "Protego."
Ginny saw the shield go up and block the spell, and her look was of superiority. "Harry," she said simply, though the meaning couldn't be clearer. Harry slowly slid off the Cloak, and looked at his shoes.
Now Ginny had known that Harry was a noble git, but seeing as how when she looked closer the footsteps were in the general direction of the forest, she apparently hadn't known that he was this much of one. He eyes narrowed dangerously. "Don't. You. Dare."
Harry looked up at her for a solid tenth of a second, and looked back at his shoes. "I have to," he muttered unintelligibly. Great. Ron had already fought tooth and limb for him to stay, and Hermione was more accepting, but helped him. In the end he had been forced to stun Ron.
"What's that?"
"I have to," he said, louder this time. Ginny shook her head.
"No, you don't. We're all fighting for you, we believe in you," she said, and the last part sounded even… pleading?
He just shook his head, and she waved over a helper for the injured girl, and walked over to him. He was surprised when she took him into and embrace, and looked into his eyes, using her fingers to lift his chin slightly so she could.
His eyes were full of guilt. Her eyes were full of fire, yet sadness.
"Please," she said. "I already lost a brother. I don't want to lose you too."
Her voice this time was complete sorrow, and it cracked with the last three words. This was when he knew he wouldn't go if she continued. So he kissed her.
Her eyes widened, and she was limp for a few seconds, but then she melted into the kiss, closing her eyes. She fell so deep into the kiss that she didn't notice Harry's hand moving into his pocket, grabbing his wand…
"Incarcerous."
Harry watched as a look of deep betrayal crossed her face. He knew that his face must have regret written all over it. "I love you," he said, and he stepped back.
Ginny seemed to get over the momentary shock, and her eyes widened.
"No! Harry!" He slipped the Cloak on. "Harry! No!" He started walking. "Harry!" Her voice was pleading. "HARRY! NO! PLEASE! I LOVE YOU! PLEASE! PLEASE!" Her voice cracked one final time, telling him that she was crying, and her voice was panicked now. He focused on her voice, and it was the thing that kept him moving. She cried out no more to him, but called for Hermione, for Ron, for Molly…
But he didn't stop once, didn't look back. He did nothing but walk until he was out of hearing range of her voice, and he pulled a small Snitch out of his pocket...
