"Get out."

"Molly, I…. Please…"

"Get. Out." Her voice was steady as she stared up at the consulting detective, but her doe eyes betrayed her pain. Sherlock gulped audibly as she closed them to stop the tears from spilling out.

When she finally looked at him again, her eyes were completely void of emotion. Gone was the love and admiration he had become so accustomed to seeing. Even disgust and doubt would be better than nothing at all.

"If you would just let me explain, Molly…."

She laughed at that, a bitter, harsh sound that caused his heart to constrict painfully. "What, exactly, is there to explain, Sherlock? Your dead ex-lover, who happens to not be dead after all, comes dashing back to London, and, just like that, you're rushing off to her side! Tell me, did you think of us at all before jumping into her bed?!" A tear escaped, and Molly turned away from him in an attempt to hide her heartbreak.

"It was a mistake! It only happened once, and I left as soon as I came to my senses. I swear, Molly, I never wanted to hurt you!"

"Well, maybe you should have considered that before you slept with her! How could I ever trust you again? What about the next time she strolls into town?" Her shoulders were hunched over as she sobbed, Sherlock's guilt eating away at him as he saw the true damage his actions had done. He was struck by the overwhelming need to fix this, whatever means necessary. He didn't know what he would do if he lost Molly. The idea was unimaginable.

"I promise you, Molly, it will never happen again! Please tell me what to do. What do I need to do to make you trust me again?!" He walked towards her, reaching out a hand to stroke her hair, but pulled back when she cringed at his proximity. Finally, she turned towards him. Gone was the impassive expression. Instead, she looked crushed.

"I don't think you can, Sherlock," she spoke quietly, walking over to retrieve her jumper from the sofa. "Since you won't leave, and this was originally your flat, anyway, I suppose I'll have to stay with John and Mary for a few days. At least until I can find my own flat. Please don't try to contact me."

He stared at the spot she had recently occupied, trying to convince himself that he had not shattered the only woman who had ever truly mattered to him. Maybe he would wake up from this nightmare to find Molly snuggled against his side, sleepily smiling up at him as he placed a gentle kiss to her temple. Maybe he would wake up to find he had not betrayed her with the Woman, and Molly still loved him.

He heard a faint clink from behind him, and pivoted in time to see her placing his grandmother's engagement ring on the table. Molly balled her fists, gathering the courage he knew she possessed in order to leave him. She slowly walked to the door, every step seeming to take more and more effort. She stopped as she reached the entryway, however, placing a hand on the doorknob.

Sensing his last chance to do something, anything, to make her stay, Sherlock threw caution to the wind. "Molly, I–"

"Goodbye, Sherlock," she interrupted sadly before pulling the door open and stepping out. As the door closed behind her, he felt an acute feeling of loss, knowing the door had shut on their relationship as well. He moved over the window and watched as his fiancé slipped into a taxi and out of his life. He noticed a wet sensation on his cheek, reaching a hand up, not really surprised to discover he was crying.

"I love you," he spoke into the empty flat, finally daring to say the words he had been unable to utter during the entirety of their relationship. "I'm sorry, Molly."

The End?

I originally posted this little ficlet on Tumblr, and asked if anyone would be interested in me turning it into a series of drabbles. The response was overwhelmingly in favor of this, so I will be continuing this story.

That being said, I cannot promise a happy ending for our couple, which kills me a little. I haven't plotted that far ahead.

To be honest, I've been in a very melancholy mood lately, and this is how I coped. I'm also sick of the stories where Sherlock cheats on Molly with very few consequences. I don't believe Molly would just forgive him. It will take time for her to trust him again.

Please let me know what you think. You know I love reading your reviews!
