A/N: it's NOT a multi-chapters story, it's only a one-shot but it might turn into a one-shot collections if other ideas come to my mind. The story pops in my head while I was eating - almond-vanilla-chocolate… (Well you don't need to know that) - Ice cream. I think that my brain function well when it's freeze : )

Hope you enjoy it

Addison walked slowly toward the elevators with her heart fall of sadness, when she watched every wall, every corner, and every employee. Even if she was leaving Seattle Grace with bittersweet memories and life has not always been easy for her, she has once started to consider Seattle home when she has imagined that her marriage will survive.

She wanted for the elevator to arrive and when the doors opened, she almost laugh aloud when she saw the person for whom she has left everything to come to Seattle, and today she was leaving the rainy city because of the same person.

She took a deep breath, moved inside then stood as far as possible form her ex-husband.

"I've heard today is your last day." Derek suddenly said.

"Yeah." A cold and uncomfortable silence appeared between them after that.

"I'll miss you."

Addison turned and stared at him with disbelief and anger. "Really? You'll miss me?" Addison hissed.

"Of course, we've been married for eleven years, not having you in-"

"Shut the hell up! Stop lying, you won't miss me you glad that the wicked witch of the west is getting out of your life, so you can have your happy end with the twelve years old."

"Addie..."

"You miss the person that you care about and love Derek, and we both know that I'm the top position on your hate list."

"I'll always care about you." Addison burst out laughing but Derek was not stupid to think that it was a happy laugh.

"You're so funny Derek, you care about me..." She said pointing at her. "Well...I don't know what to say, seriously you care?"

"You will always be family-"

"Cut the crap please. Do you think that we are in a Disney movie where at the end, enemies and friends come together, to sing and have a happy end? I'm no longer family dear ex-husband of mine. We'll never celebrate anniversaries, birthdays, holidays and whatever again, DerekandAddison is dead."

"I never meant to-"

"What? TO WHAT DEREK? To run away and leave me alone while my life fall into pieces? To break my heart? To fall in love with an anti-Addison that you met in a bar? To treat me like trash and humiliate me when I was trying to get my husband back? To cheat on me while I was just a few meters from you?" Addison shouted with tears falling down her cheeks but shease. does not seem to realize. Derek raised a hand to touch her but she stepped back.

"I'm so-" Addison raised her hand to stop him.

"I might be an adulterous bitch but what you've done is worst, you've fall in love with another woman and trust me Derek it's the worst thing that you can do to one who loves you." Addison sadly said. "How do you do it Derek? How do you stop loving a person you've spent eleven years with? I would really like to have the instruction. How do you decide that the person who has always love...care...encourage...who has always...who would have given her life for you...how do you decide that the person is less important than a woman that you've just met? A woman you don't even know? How do you end a marriage for a relation that you don't even sure will survive?"

Derek looked at Addison, dumbfounded. He does not what to say or do, so many questions that he does not know if he has the answer to.

"I don't-" The doors slides open before he has the time to answer.

Addison chuckled drily. "This is the end and still so many unanswered questions. Don't worry, I don't expect an answer from you, it's too late for that." Addison stepped outside then turned to look one last time at Derek. "But I want you to answer one question, just only one question...Does she worth it? Does Meredith Grey worth everything you've done for her?"

Instead of answering Derek just stared at her during which seems like an eternity. Finally, Addison shook her head and gave him a sad smile. "Goodbye Derek."
