A/N: Hey you guys! I'm back with this new story, it's based in the third season of the show, the difference is that we won't see the very pacific divorce Addison and Derek had on the show because there's no such thing like it, here you'll see how messy things could be after it and if there's a way to fix things during this painful process. I'm co-writing this story with the awesome BadassGenius. We really hope you like it

Addison Montgomery-Shepherd had always been a very successful woman, she always knew exactly what she wanted and how to get it. When she walked in to a room every single person could notice it and everybody who knew her could say she had the perfect life. She got married during Med School with this very handsome man, also a doctor. They were both world-class doctors in their fields, everybody could say she had it all

But in this particular night Addison herself realized that everything that everybody thought about her life was completely a mistake. She had known that her marriage was falling apart since the moment she cheated on her husband, but now she was trying really hard to fix things on her marriage. She knew that Derek wouldn't forgive her easily but she was a fighter, she wouldn't give up on Derek. But tonight she knew that her whole life was about to change in a way she never thought. She had never imagined that her husband would have preferred a slutty, not even pretty, intern over her.

Since she had moved to Seattle, particularly those last few days she could swear that she and Derek were gonna get over "the affairs". In the last few weeks, she had thought that they were making progress in their relationship. After he apologized for the way he treated her in New York and promised he was working out, Addison really believed they were finally coming out of this dark place where they had been in this last year.

But tonight she figured she was wrong, few days ago she was starting to suspect there was something between her husband and Meredith Grey. Addison knew that her husband and his mistress had been fooling around even after Derek decided to stay with her but she decided to just ignore it. She felt afraid that she could lose her husband and this time forever. The day of the prom she was happy that Derek asked her to go with him, but her happiness didn't last very long. After finding someone else's panties in your husband tux, you know that it is really over. And the feeling that gets you is something so painful that hits your soul so badly that you wish you could die.

The following days after that famous Prom night, she had to face the breakdown of her marriage with someone she had spent all her adult life with. Now she had to let it all go, she knew that Derek wasn't the same guy she got married to but she still loved him as much as when she first saw him. That would have never changed. Deep in her heart, she also hoped that he still loved her the same way she loved him but after Prom night Addison was sure enough that his feelings for her had moved, that his love for her wasn't there anymore.

But realizing that Derek didn't feel the same way now, seeing him with his now girlfriend in every single place of the hospital made her doubt everything she had thought about her marriage. She started to realize that she was only an obligation and that Derek was just trying to be the good guy trying to make it work.

Seeing Derek and Meredith together made her sick, she wanted him to be happy just not with his mistress. Since she had found out that her husband cheated on her, she was broken. She needed to feel like there was still a reason to live for, she needed to feel loved and wanted but she knew that Derek wasn't the guy for this, not anymore.

So she did what it was expected, after getting severely drunk, she called Mark Sloan to tell him everything that had happened between her and Derek. He immediately left everything and took the first plane to Seattle, he knew that Addison needed him

She slept with Mark as soon as she saw him walking through the door of her hotel room and she couldn't deny that Mark made her feel a lot better about herself, but she was still thinking about her failed marriage, legally she was still married and she knew it was wrong, but at this point she only wanted to forget Derek

The next day, she decided it was time to talk to Derek about the divorce but as soon as she checked her e-mail she saw an email from Derek telling her the details about the divorce and the day when they were supposed to meet the lawyer to sign the papers. That was all, not even a greeting or even a call. It was like he wanted to forget her as soon as possible because he wanted to move on with his own life, with this new girlfriend of his.

At the hospital, she always saw Derek but they didn't talk. Not even when Mark, few days after Addison's call, decided to go to work there at the Seattle Grace Hospital, and Derek wasn't exactly happy about this sudden decision of Mark.

After a week avoiding each other, mostly because she didn't want to see Derek with Meredith now that he was free to be in a relationship with her, both Addison and Derek went to the meeting with their lawyer to finalize their divorce and finally do what they wanted to do, move on with their lives

"Derek says that neither of you brought your assets into the marriage" Mr. Andrew Foster, the lawyer of both Addison and Derek, cleared

"Well, I had my trust fund. And a sparkling personality. And the futon couch" Addison said, trying to joke. It was a very sad day for her and she was trying her best to not to fall apart

"Yes, Addison had a very ugly, very heavy futon couch" Derek mentioned

"What happened to that couch?" Addison asked, knowing the answer already

"We gave it to Mark. She can have him." Derek said, looking at the lawyer. He thought that he might actually feel uncomfortable with this but being a divorce lawyer for twenty year this was absolutely nothing

"I don't want him" Addison said, looking down

"Ok, so that's settled. What else?" Derek immediately said, he needed to leave this place as sooner as he could

"Aside from Addison's trust fund which will remain in her name, we'll spilt everything, stocks, bonds, 401K's down the middle. The only thing that gets complicated is the real estate" Mr. Foster told the soon-to-be-ex-husband-and-wife, knowing that this was always the part when it got really difficult to split the assets

"Well, let me make this simple" Derek started, getting the attention of both Addison and Mr. Foster "I'd like to keep my trailer and the land in Seattle. Addison can keep the rest" Derek said, reading the divorce papers. All he wanted to do was finish this today, he didn't care about anything else. He wanted to leave everything behind his back as soon as possible.

"That's the house in the Hamptons and the Brownstone overlooking Central Park. That's very generous of you. So, I'll re-write the divorce papers and all I'm gonna need is your signatures to finish the process" Andrew told his client nodding and smiling professionally

"Hold on" Addison interrupted the lawyer "I don't want Dr. Shepherd's agreement" her voice came out rougher than she actually wanted.

"What are you talking about, Addison? I'm leaving you the house in the Hamptons and the Brownstone. What else would you want?" Derek slapped. He was confused, he was sure Addison would take his offer. After all, she had never liked Seattle.

"I don't live in New York anymore, so I'm gonna need a place to stay here in Seattle. Why should I buy a new house when there's a whole land waiting for me?" She admitted, looking at him straight in the eyes.

"What? You hate the land, Addison! Since you've moved here all you have done is complaining about it! You can't be serious" he raised his voice and started to gesticulate with his hands like he always did when he was nervous.

"Dr. Montgomery, are you sure about this? Dr. Shepherd was quite generous with his agreement, you wouldn't find anything better than that" Mr. Foster tried to make Addison take this but she just shook her head

"I want the land in Seattle, he can keep the trailer... You know what? I take that. I also want the trailer, I've always wanted to blow it myself so it'd be fun to do it... And Mr. Foster, I'm sticking with his last name so you don't have to call me Dr. Montgomery"

"Addison, what are you doing? Why are you acting like this? I thought we would be civil about this" he growled.

"You and I civil after this? Come on! How can you even ask me to be civil with you? After the way you've treated me! I found your mistress' panties in your jacket, you can't ask for an easy way out, Derek! So yes, I want the land in Seattle. You can't always get want you want, Derek" she hissed. Her eyes were furious. Nobody knew that, deep inside, Addison was shattered and she was trying her best not to breakdown.

"Can you give us a minute alone, please?" Derek asked the lawyer, who simply nodded leaving his two clients alone in the office and knowing that they were about to have a huge fight. After all the divorces he had worked with, he knew that there was no such thing as a friendly divorce, and he knew that if they were gonna fight for the real estate, it wasn't gonna be easy.

"I refuse to tell you anything if the lawyer's not here" Addison simply said to her soon-to-be ex-husband

"Just listen to me. I know I've screwed up but we were living a lie, Addison! We didn't love each other anymore, the only thing we needed to do was accept that our life together was over a long time ago. I know I shouldn't have slept with Meredith but we don't really need to do this"

"I did love you, Derek. That's the problem. You didn't even try to make it work! You've made me go through hell these last months! You've treated me like if I were shit under your shoes and I kept my mouth shut because somewhere deep down I knew that I deserved it. If you didn't want to be with me why did you even take me back in the first place? Oh right! You wanted to be the good guy who makes think everybody he forgave his cheater-wife. You wanted me to be the adulterous bitch who doesn't give a shit about her husband and then all of a sudden comes here to destroy the new perfect life of her so called husband!" she quickly cleared her voice because she was starting to lose it. Her eyes had started to burn due to the tears she had been holding for so long.

"You know that's not true, Addison" He lied. She was actually right, she knew him too well to even know what he hid from her. "I, I did want to make it work but-" Addison interrupted him

"But it wasn't enough because I can't compete with Meredith Grey! I wish… I just wish you did never give me hope! Call me naïve if you want, but I did want to make things work. Apparently, you've never wanted it. So, you know what? Go back to your perfect twelve years old girlfriend!" She felt like she wanted to cry but she couldn't allow that, not right now "You know what? You better find yourself a lawyer since Mr. Foster has always worked for my family"

"You know there is no reason to do this"

"Let's see what the judge says about that… You've made my life miserable this last month, Derek! You made me think I had a chance when I never had it, now stick to the consequences. You've ruined my life, Derek Shepherd, and I'm so going to ruin yours. Deal with it." she stated. Her eyes, full of repressed tears, were shining a deep glacial light.
