Severus and Lily, a history

He was a shadow, dark and alone,
She was sunlight, brightly shown,
He cursed his life while she held hers dear,
He denied it, while she thought it was clear,
Their first stolen glances, there was a spark,
Then suddenly light flooded the dark,
She held his gaze, green eyes bright as day,
His black eyes flickered, and he looked away,
She reached out to him, completely unarmed,
He shied away, too many times harmed,
Though time passed, he kept her in mind,
How sweet she was, and how very kind,
Then one day, she gave him a clue,
She told him she loved him, he didn't know what to do,
He was confused and suprised, even slightly afraid,
Amazed overall by the choice she had made,
She stood there, waiting for him to respond,
Waiting to see if he was willing to bond,
He stumbled on words, unable to think,
Blushing and staring, unable to blink,
Grasping onto a feeling he never knew,
He relized then that he loved her too,
But he didn't say it, He was too scared,
So he left her thinking that he never cared,
She was hurt and upset, he felt guilty inside,
He avoided her, trying to hide,
Tear filled eyes, stuck in his head,
As well as the things he wished he had said,
But each time he saw her, she wouldn't go,
She was the same girl he met years ago,
She was patient, she was kind,
She was the girl that he left behind,
No more smiles betwixt them, he turned her away,
He went back to the shadows, sure that's where he'd stay,
She reached out to him, offering one last chance,
A friendship or love for him to enhance,
He looked away holding invisible tears,
His chances conquered because of his fears,
When he was in trouble, she rushed to his side,
In his anger, he hurt her, she cried,
Tears of pain, she'd never cried before,
He hurt as much as her, if not more,
The way she lashed back after what he had said,
Filled him with anger, regret and dread,
He felt too guilty to try to explain,
To face the trust he had so ruthlessly slain,
He plucked up his courage and wiped his face dry,
But upon finding her, again did he cry,
She was tightly embraced by another man,
He turned on heel, sobbed and ran,
He locked up his heart, threw the key out the door,
And he was lost forevermore
