A/N: So this is just gonna be a series of one-shots. They'll probably be four, but I may not have time to write that many, or I may think of more, you never know. Here's the first one, anyways. It's Addek, basically how they fell apart, but then fought to stay together again. That's gonna be the main plot of all the one-shots, by the way. Please review, and any ideas for how they could fall apart are welcome, I do have a few but they're kinda boring and have probably been done before. New ideas equal love:)

Thanks Zoe (QueenSatan) for Beta-ing. You rock:)

Disclaimer: Grey's? Not mine. But I am getting the DVD in three days. Yay!!

Derek sighed as his phone began ringing again. The dull tone had become so well known to him that he hardly heard it any more. Grabbing it, he stared at the Caller ID for a few seconds before throwing it down on the floor next to him. He didn't know the real reason why he was dodging her phone calls, but he did know he'd taken it too far now to stop. Running a hand through his hair tiredly, he leant back on the pillow behind him.

"Great," he thought. "Another night on an on-call room bed."

-----------------------------------------------------------

"Damn it, Derek," Addison slammed her phone shut and sat down on the edge of her bed. Why was he avoiding her? Why didn't he ever come home anymore? What had she done to make him want to spend so much time at the hospital rather than at home with her? She was tired of spending every night alone when she should be spending it with her husband. She'd had countless conversations with his answering machine, and not once had he called back. She wiped the tears that had fallen down her face away and lay down on the large bed. She pulled the covers up over her body and let her head sink into the pillow, and fell asleep to the sound of her own tears.

-----------------------------------------------------------

"Derek, you look tired," Mark commented as the two men made their way towards the hospital cafeteria.

"On-call room beds don't exactly give me best night's sleep," Derek yawned.

"Well you could always go home," Mark suggested, knowing it'd take more than that to get Derek to see that Addison needed him home.

"It's too late now," Derek said.

"It's never too late," Mark replied. "Why are you doing this, Derek? Why are you being so distant?"

Derek stopped walking and turned to face his friend. "I'm not being distant."

Mark raised his eyebrows. "You never go home. She misses you. She need you back."

Derek sighed and dropped his gaze to the floor. "I don't know what I'm doing any more, Mark. I don't mean to be so distant, I just can't stand the thought of losing her."

"Why do you think you're losing her?"

"I'm scared that if I go back now, she'll be so mad at me and she'll tell me to leave or she'll leave herself. I can't lose her, Mark. She's everything to me and I'm so scared she'll realize she can do better and leave," Derek sighed again and looked back up at Mark.

"She loves you, there's no way she's going to leave you. She wouldn't care if she could get Russell Crowe, she'd still choose you. You're the one she wants, Derek, you just have to make things better," Mark said, hoping he would listen.

"What can I do?" he asked.

"I have the perfect idea."

-----------------------------------------------------------

"Don't give anything away. Don't give anything away," Mark muttered to himself over and over again as he walked up the steps to Derek and Addison' house. He knew if he gave anything away now, it would blow any chance of the plan working.

He knocked on the door, even though he had a key, he never used it, and waited for Addison to open it. After a few moments he saw her approach the door and open it slowly.

"Hi, Mark," she said, the tiredness evident in her voice. He took in her tear-stained cheeks and red, puffy eyes.

"Hey Ads, how are you?" He asked, moving past her to walk into the house.

"Fine," she shrugged, closing the door.

They walked in silence through to the living room, where they both sat down facing each other.

"He's still not picking up his phone. I don't know what else I can do. I've tried everything I can think of," she wiped a stray tear from her face.

"Just keep going, Addie. He'll come round soon, I'm sure of it," Mark smiled warmly.

"I'm not so sure of that," she shook her head. "I just don't know what I've done wrong."

"You've done nothing wrong. This is all on him, he's the one missing out."

"Not really, I'm the one who's here alone when he's at the hospital. There's obviously something happening there that's better than staying here with me," she sighed and put her head in her hands.

"Addie..." Mark drifted off.

"Can you just leave me alone for a bit?" She whispered.

Mark nodded. "Okay," he said and got up, kissed the top of her head gently before leaving the room. He hoped Derek would take his advice before Addison really gave up.

-----------------------------------------------------------

Derek took a deep breath. It was the first time he'd gone home in ages and he wasn't sure how Addison would react. He was sure she'd be mad, but hopefully she'd be so happy to see him that the madness would just fade away. He had it all planned in his head, and he kept telling it to himself. 'Don't act like nothing's happened because sooner or later we'll have to talk about it. Don't get mad, even if she does, because it'll only give her more of a reason to hate me. Don't think it's all going to go back to normal now, we have so much to sort out.' He shook his head and ran a hand through his hair. What was to say she wouldn't throw him out immediately, without giving him a chance to speak? 'No,' he thought. He couldn't think that way. It was going to be fine.

Finally he put his ket in the lock and pushed it open slowly, half expecting something to fly at him. But he was safe, at least for now. He closed the door and walked through to the living room where Addison was asleep on the couch. He sighed. 'She looks so vulnerable.' What had he done?

Carefully he walked over to a cupboard and pulled out a blanket. He walked back over to the couch and lay the blanket over her, not sure if he wanted her to wake up yet or not. He watched as she moved slightly when the fabric touched her skin, and then settled back down. He let out a breath and sat down of the chair facing her.

He knew he needed to explain everything to her, to explain why he'd been so distant the last few months. It wasn't that he didn't love her anymore, more that he was scared she didn't love him. The first time he'd met her he'd been so amazed by how beautiful she was, and also by the way she acted. She wasn't the kind of girl to show off her beauty, and she never looked twice at the guys who constantly looked at her. Both he and Mark had wanted her to notice them. Mark, however, learnt his lesson after hitting on her at a school charity party. Derek had become friends with her almost immediatly (Mark had too, but he'd kept more of a distance at first), and had began falling for her soon afterwards. Unbeknown to him, though, was that she was falling for him too. It had taken them eight months to admit their true feelings to each other, but when they did they were happier than either of them though possible. They dated for two years before he proposed after a romantic meal and walk through Central Park. Five months later they were married and happily in love. Nobody ever thought anything would tear them apart, they were the 'perfect couple'. But now Derek realized he was the one who'd thrown all of that away. He was the one who'd pushed himself away from her, he was the one who'd thrown away the best thing that had ever happened to him.

He gasped slightly as she began to stir, and her eyes fluttered open. She took a few moments to take in her surroundings, and she sat up quickly when she saw Derek facing her. She yawned and raised her eyebrow at him questioningly.

"Derek, you're..." she hesitated. "What are you doing here? You're never here."

He broke eye contact with her and studied the floor. "Addie, I'm sorry."

"For what?" she asked, wanting him to admit that he was wrong and explain why he'd been so indifferent towards her.

Derek shook his head. "Addison I want to explain this all to you but I don't know how. I need to make you see that this was nothing to do with you."

"Just tell me Derek," she pleaded.

"Just give me a while to understand in myself, Addie, please," he replied.

"How can you not understand it? You're the one who's been spending every day at the hospital without coming home. I've been alone here wondering what the hell I've done wrong for you to want to avoid me. Can you blame me for wanting to know why, Derek?" She stood up and walked to the kitchen.

Derek took a deep breath and followed her. "Look, Addie, I'm sorry. I don't understand why I did this but I know I can't stand to have you mad at me."

"I'm not mad at you. Well, I am. But I'm more disappointed and confused," she looked up at him.

"Well I can't stand that either."

"Then tell me what I did!"

"You didn't do anything."

"Then why are you doing this?" She was shouting at this point and tears were beginning to run down her cheeks.

"Addison don't cry," he reached out to her.

"You're the one making me cry," she pushed his hand away and moved to the other side of the room, facing out of the window away from him.

"Addison-"

"No! Don't talk to me until you can tell me what the hell I did and what you were thinking," she said, not turning around.

Derek sighed and ran a hand through his hair. "I'm just so scared of losing you. I'm scared that you'll realize you could do better than me and leave. I love you, Addison. I love you so much it scares me, because I know without you I'd be nothing. So I thought if you never saw me you'd fight for me, which was stupid because I know you're not strong enough for that. I just brought back all your old insecurities that you weren't good enough, and that I was going to find someone else," he paused and took another deep breath. "I just wish I could take back these last few months, I would never have been so distant, because I hate how much I've hurt you," he finished and took a few steps towards her. When he reached her he wrapped his arms around her waist and buried his head into her neck.

"You were never losing me," she whispered.

"I know. I'm just stupid," he smiled against her skin and kissed her neck.

"Derek, you know it's not this easy to make everything better, right?" She asked as she turned around to face him.

He nodded and rested his forehead on her's. "Yes, but it's a start," he smiled again and kissed her lips. They were getting there. They would be fine.
