Author's Note: I started this chapter knowing where the story was eventually going, but having no clue what exactly was going to happen in this chapter, so hopefully it came out okay! Once I started it actually began to flow in my head and ended up being pretty long. Did I make Addison too weak/cooperative/something? Let me know if I did and I'll work on it! This is my first GA fanfic so I'm trying to get into the characters' heads, but she's complicated. Please read and review!

This new discovery made things more difficult between Derek and Addison. She expected him to yell and scream and tell everyone else what happened. She expected him to throw obstacles in her way at work and disagree with her at home. However, none of that happened. He ignored her at work and made sure not to be in the trailer at the same time she was. It was basically the more adult version of the "silent treatment." She was constantly on edge, waiting for the moment when he'd announce her infidelity to everyone or blow up at her over something simple and then start screaming about Mark. Mark, every time she heard anyone mention the name a knot formed in her stomach. She still hadn't even begun to think about what she was going to tell him, or if she was going to tell him at all.

'Maybe this is his form of punishment,' she thought at first. 'He wants me to be nervous over what might happen next.'

After a week of barely talking to each other, Addison decided to confront Derek. She pulled him into an empty exam room.

"Derek, why haven't you yelled at me yet?"

"What are you talking about?"

"You know what I'm talking about!" she hissed.

"Well I don't think you want to talk about it here. I'm sure it's not something you want everyone to know about."

"That's true, but we haven't dealt with it. We need to deal with it. This isn't something you can ignore and it'll just go away in a few days."

"I can't have a conversation about this. I forgave you the first time you slept with him and I was generous enough to forgive you the second time. But this is too big of a mistake for me to ignore. It affects the rest of our lives- yours, mine, Mark's, and that baby's."

"Maybe I don't have to tell Mark. Maybe we can just tell everyone it's our baby."

"You know you have to tell him."

"I know." She looked down at the floor.

"Do you think I'm going to pretend to be happy? Pretend that we're having a baby together Addison!" his voice got louder. "No. I'm not going to say anything because I have nothing to say to you anymore. This thing- us, our marriage- is over." He turned and walked out.

Addison leaned against the wall, alone in the room, unsure of what to do. He was Derek, the love of her life; he was supposed to forgive her. She knew she made a mistake; she just hadn't realized how big the consequences would be. She thought there was a chance that Derek would still be happy about the baby since they had tried to have a child in the past and hadn't successfully conceived. At that moment all she felt was hurt and confused, but she wasn't going to let Derek see that. She still had a job to do and there was no time to feel sorry for herself. She put on her bravest face and went to find Derek. She found him, fairly easily, at the nurse's station.

"Fine. I'll be out of the trailer by tomorrow," she whispered and then walked away.

He stared after her, half of him longing to go back to the way they were and the other half seething with anger.

She went back to the trailer and put all of her stuff back into her suitcases and put them in her car.

After work, having no where else to go, she decided to check back into The Westin until she had a chance to find an apartment. She walked in to the lobby, pushing up from her eyes into her hair as she entered.

"Dr. Shepherd?"

She cringed, not wanting to face whoever she ran in to this time.

She turned around. "Dr. Stevens, hi. What are you doing here?"

"My cousins are visiting so I went out to dinner with them and then we hung out in their hotel room for a while." She paused for a second. "Wait, why are you here?"

"Oh, um…" She tried to come up with a good lie, but her mind went blank. "Derek and I are having big problems right now…I can't stay with him in the trailer and everyone else hates me, except the Chief and Adele, but they're busy enough, and Dr. Bailey, but her and Tucker have the baby so their house is full, and I didn't know where else to go, so…" she rambled on, trailing off at the end.

She stared at the floor, trying to blink back the tears that were forming pools in her eyes. She wasn't supposed to seem vulnerable, especially not in front of the interns.

She looked up again, allowing the tears to cascade down her cheeks like a waterfall.

Izzie looked at her sympathetically. She also seemed a bit uncomfortable and unsure of how to react. Addison was her superior at work and the woman whose husband broke Meredith's heart, but now it seemed that her heart was broken too.

Addison spoke again, "I- I'm sorry, it's just…"

"No, it's okay. Don't worry."

"But there's more."

"It doesn't matter. You can talk when you're ready."

Addison nodded, feeling grateful.

"Come on, we have an extra room. You can stay with us for a while."

Addison tried to wipe her tears as she was shaking her head. "No, no, I can't."

"It's fine, really."

"But you're my interns, well not my interns specifically, but…and it's Meredith's house. Even if George agreed, there's no way she'd let me stay there."

"She will. She knows what it's like to have your heart broken, she'll understand."

Addison calmed herself down enough to drive and then followed Izzie to the house.

As luck would have it, both George and Meredith were sitting on the couch, watching a movie when Izzie and Addison walked in the door. They both looked up, definitely surprised to see the She-Shepherd in their house; they had seen the He-Shepherd there before obviously, but never the female one.

"Hey Izzie, um…Dr. Shepherd," Meredith greeted them, just staring. She had never seen Addison look anything but perfect. However, tonight she looked tired and Meredith could tell she'd been crying because her eyes were red and her mascara smudged.

"Hey guys. Can I talk to you for a minute? In the kitchen…" Izzie started walking, but then turned back to Addison. "We'll be right back, just sit down and make yourself comfortable."

"What is she doing here?" Meredith asked, somewhat annoyed.

"I know she's not your favorite person, but I saw her at the hotel earlier and she looked so sad and so alone. I don't know the details, but she and Derek aren't doing well right now. I'll find out whatever I can tomorrow, but right now I think we should just let her stay in the extra room. It seems like she's had a long day. I told her I'd check with both of you first though."

Meredith and George looked at each other and then back at Izzie, still not saying anything.

"She didn't want to come. She said you wouldn't let her stay, she thinks you hate her."

"Well I don't think she likes me very much either," Meredith responded.

"I didn't either at first, but now I think she's trying to get along with you, if you'll give her a chance. You know how hard it was when Derek broke your heart. Now he's done it to her, so if anyone can understand how she feels, it's you."

Meredith sighed, unsure of how to feel about this. "Fine, it's okay with me if it's okay with George."

The two girls turned to look at him.

"Me? Oh, it's fine with me." George was good-natured and got along with most people, so they didn't expect him to have a problem with it anyway.

The three of them walked back in to the living room and found Addison sitting uneasily on the edge of the couch, still wearing her coat and clutching her purse.

George spoke first, "I'll go get your bags and put them in the spare room."

"And I'll show you where the room is, and the kitchen and bathroom and everything," Meredith added.

Addison nodded and stood up. "Thank you."

She then followed Meredith out of the room. After Meredith had finished showing her around, she brought her to the spare room. "And this is where you can stay. George already put your stuff in here. Oh, and I recommend getting up fifteen minutes early to avoid a fight for the shower. George may complain about living with two girls and having to buy tampons, but he's the one who takes the longest to get ready in the morning! Don't tell him I told you though," Meredith joked, laughing.

Addison smiled. "I won't be staying here long, I'm looking for a place as soon as I have some free time, so don't worry, I'll be gone—"

Meredith cut her off. "It's okay." She looked down for a minute, thinking, and then spoke. "I'm sorry about whatever's going on with you and Derek." Part of her wanted to ask what had happened, but she realized it wasn't her business right now; the other part of her wanted to be comforting and offer to listen if Addison wanted to talk, but she knew that Addison probably wouldn't want to talk to her of all people.

"Oh…thanks."

"I'm gonna go back in the living room and we're gonna watch a movie, if you wanna join us," Meredith offered.

"Maybe, but I think I'm just gonna rest for a while."

"Okay." She started to leave, but something made her turn back, probably the fact that she too had been broken recently, and by the same man that Addison was upset over, so she thought she understood the pain. Of course, she had no clue that Addison had an even bigger secret than what happened between her and Derek. "If you ever wanna talk…about whatever, I'm here. I know you probably don't want to talk to me, but I'm sure Izzie and George are more than willing to listen too." She turned back around and continued walking.

"Meredith?" Addison called after her.

"Mm-hmm?"

"Thank you. I really appreciate all of this."

Meredith just smiled and then headed to the living room.

A few minutes later George, Meredith, and Izzie were all sitting on the couch with a bowl of popcorn when the doorbell rang.

Addison held her breath, waiting to see who is was, hoping it wasn't Derek. He would spill all the details and she hadn't had a chance to explain yet. She figured that if he told them what she'd done, they wouldn't be acting so nice towards her and she would end up back at the hotel.

She slowly exhaled when she heard voices coming from the living room and realized it was just Alex and Cristina. Probably coming over to watch that movie Meredith mentioned, she reasoned.

On another night she may have decided to go join the interns, but tonight she just wanted sleep.

After forty-five minutes of tossing and turning, she decided to see what was going on in the living room. She changed out of her pajamas and into comfy sweat pants and a top and headed down the hall.

"Hey guys," she said, trying to smile, as she entered the room.

All five of them stared back at her. None of them had ever seen her look this casual. She had no makeup on and her hair was pulled back in a ponytail.

"Hey, coming to join us?" Izzie asked.

"Yea, I think I will." She crossed over and sat on one of the chairs.

Cristina and Alex just looked at each other and shrugged. The others had told them that she was staying there for a while, but neither of them fully believed that she was just being so casual and Meredith didn't even seem to mind that she was there.

"Hey Mer, can you come into the kitchen with me and help me get some drinks?"

"Sure," she replied, pushing herself up from her current position sitting cross-legged.

Once they had left the room Cristina spoke, "You're okay with this?"

"With what?"

"With the She-Shepherd staying at your house?"

"Oh, yea. I wasn't sure at first, but it's fine. I mean, she's only been here like two hours, so we'll see how it goes. But right now it's fine."

"Whatever you say," Cristina answered, grabbing a bottle of tequila and heading back to the living room.

Meredith rolled her eyes and followed.

Alex started pouring shots for everyone. He handed one to Addison.

"Oh, no thanks," she said, pushing it back to him.

"Come on," Izzie coaxed. "You can drown your sorrows in alcohol."

"It helps," Meredith added, nodding. "Well, until you do something stupid or have to deal with a hangover the next day."

"I have to work tomorrow and hangovers give me terrible headaches, so I'd rather drown by sorrows by eating some of this ice cream." She grabbed a bowl and a spoon.

Izzie watched her carefully and wondered if this had anything to do with whatever it was that happened that Addison hadn't told them.
