So here we are with the start of a new story, as with all my stories we are talking 100% pure Sherlolly but I am aiming to bring in another crime plot line as I did last time.

As some of you will have guessed the inspiration for this story has come from the song Say Something by A Great Big World. There have been other fics using the Say Something title though and I wanted to have a slightly different theme for the story hence Saying Goodbye. Don't worry there won't be too much angst though. Rated M for smut, smut and maybe some more smut, you know my style by now.

I own nothing but the idea, everything else belongs to ACD, Moffatt and Gatiss.

Chapter 1

It felt like it had been raining for days. Molly sat in the morgue listening to the rain hitting the basement windows. If she looked out all she could see was grey clouds. It seemed very trite to say it but it matched how she felt at that moment.

She sighed as she sat back in her chair, her hands playing with the pen she had just finished writing with. For what seemed like the thousandth time she wondered what on earth she was going to do.

It had all come to a head the previous week. Following the whole Moriarty fake jump incident Sherlock had been back for well over a year. John and Mary were back together and had had a baby girl just over a month ago. Molly had gone round with gifts and had sat holding this small new life and her stomach had twisted, for a moment she almost couldn't take a breath. Would she ever hold her own child in her arms? She'd made an excuse and left shortly after making her way back to her empty flat where she'd spent the rest of the evening crying into a bottle of wine.

She could have had that with Tom if she'd continued with the engagement. They probably would have been married by now, maybe even trying for a child of their own. She closed her eyes seeing once again the pain in his eyes when she'd broken things off, when she'd explained to him that no matter how much she loved him she loved someone else more.

Was it worth it? There was no 'relationship' with Sherlock. He didn't treat her any differently now to the day he first met her. No, that was a lie. He didn't make false compliments to get his own way, he at least respected her that much now.

She had hoped that they would be closer, be friends maybe. Yes, they worked well together, he would ask her opinion on his experiments, would listen to her observations regarding the murder victims he was called in to help investigate, she would even occasionally see him outside of work if John organised some kind of get together but that was it, and it wasn't enough. Not anymore.

She wanted to be with someone, needed companionship, the chance of children and she was never going to get that with Sherlock.

It wasn't as though she hadn't tried, she had. She really had. Two days ago she'd gathered whatever strength she had left, where he was concerned, and she'd tried again.

He'd been in the lab checking out something with the microscope, making notes. He was looking gorgeous, as ever, wearing a fitted black suit, tight white shirt open at the neck, his dark curls falling over his forehead. As she walked towards him her mouth ran dry, she almost gave up and walked away but he spoke without even looking up.

'What is it Molly? Spit it out, your nerves are distracting me.'

'Oh...I..err. I was wondering if you'd like to go for coffee sometime?'

At this he looked up, a confused expression on his face, 'I don't understand we have coffee all the time, don't we?'

'Yes, I mean no. I mean, we have coffee here in the lab, but would you like to go out sometime, for a meal...or coffee..or I don't know...' She trailed off partly wishing she had never started this but also knowing that she needed to try.

He huffed, 'I don't think that would be a good idea Molly.' With that he turned back to his microscope effectively dismissing her, without an explanation or anything. It was all she could do not to run as she left the room. She wondered if it wouldn't have been better if he'd torn her to shreds with one of his deductions, at least she'd know why he was rejecting her. This, this was just so final, so uncompromising.

So she was back to her original question, what on earth was she going to do now?

SHSHSHSHSHSHSHSH

Sherlock was at home in Baker St. The flat seemed so very empty since John had moved back out. He'd told everyone that he preferred it that way, that he was better living alone, no stupid in the room, no distractions, but it was a lie, he missed John. He was also vaguely aware that having John around was probably good for him.

John was definitely useful when it came to chatting to Mrs Hudson when she brought up tea and cake. He was good at telling Sherlock when he'd crossed a line and said or done the wrong thing, which seemed to be often. He also gave Sherlock insight into the mind set of ordinary people which often times proved invaluable. Plus now he'd got used to expounding his theories to a real life person his skull was difficult to go back to.

He didn't want to get a new flat mate though, didn't want anyone else in his life. Yes his circle of friends was small compared to most people but it was huge for Sherlock who had never had friends in his life. Up until this point he had just had his family, Mycroft had been the nearest he'd ever had to a companion, everyone else had just been wallpaper, background noise.

Now he had John (he still wasn't quite sure about Mary yet), Mrs Hudson, Lestrade and Molly.

Molly, his Molly. He knew she wanted more than just friendship from him but he couldn't understand why she would need to change the status quo. They worked well together, it was...companionship. When things got too quiet in the flat he always knew he could go and be with Molly at Bart's even if they didn't speak to each other.

He remembered back a couple of days to when she had awkwardly asked him out, just like that first time four years ago. He had been tempted to say yes, but he knew what he was like. He'd say or do the wrong thing, would hurt her all over again. What if that made her leave, or she refused to work with him anymore? No, they were better off as they were, staying friends, staying safe.

He was particularly glad though that she had broken things off with that idiot Tim though. He rolled his eyes remembering John and Mary's wedding and the 'meat dagger' reference. He hoped that meant Molly had given up on men. He didn't want her distracted, it was far better when it was just the two of them and he wasn't competing for her attention.

He paused in his thoughts, rolling back through them in his mind palace, a slight frown on his face, something unusual, unexpected even, what was it...yes, there it was. He'd been tempted to say yes.

Molly had spoken to Mike Stamford. She didn't want to leave Bart's but there was a secondment opportunity at one of the other London hospitals and she was thinking it might be a way of giving her some separation from Sherlock. After all it had worked last time. She'd met Tom when he had been away, maybe she could meet someone else, maybe not being around Sherlock all the time would help her to think of him less.

Mike had spoken to his counterpart at Charing Cross Hospital. It was maternity cover but the pathology unit there was much bigger than at Bart's. It would be a great opportunity, career-wise, for Molly and who knows, if the current position holder chose not to return after maternity leave the position might become available permanently.

She thought it through that evening as she sat listening to music and drinking yet another glass of cheap white wine. All this moping over 'him' really wasn't healthy for her, she drank alone far too much. This change could be a fresh start for her. She could be someone new, more confident, less mopey, less drunk. She giggled to herself, her cat, Toby, languidly opening one eye to stare at her from his position on the settee.

The evening started off with her feeling very upbeat about the change and all it entailed but by the time she was embarking on her fourth glass the music had become more melancholy and she sniffed as she listened to yet more lyrics which mocked her feelings for Sherlock.

It was as she was listening to a new song that she'd recently downloaded that she heard the words which really seemed to strike a chord with how she currently felt.

Say something I'm giving up on you...I'll be the one if you want me too... Anything, I would have followed you...you're the one that I want but I'm saying goodbye

Oh my God, she thought, that's it, that's what I need to say, he needs to know that I'm saying goodbye. She drank another big gulp of wine, wondering where that glass had gone before pouring herself another.

She grabbed her laptop from the side of the settee, startling Toby as she nearly fell on him.

She drank more wine as the laptop opened up, pressing repeat on her iPod so she could hear the song again. Soon she was busy writing a quick email before attaching the song and pressing send.

There she thought, it's done.

Oh dear poor Molly, is drunk dialling or emailing ever a good thing?

I'll aim to post twice a week all I ask of you guys if that you review, follow or favourite. Let me know you are out there and wanting more.
