This is something I thought about after watching clips and Derek and Addison from the episode 3x08. Hope you enjoy and let me know what you think. I may decide to continue or just leave it there as a short one shot.
Addison felt the tears trail down her cheeks as she threw her wedding rings over the side of the ferry. She pictures her wedding day and Derek putting the rings on her finger and promising to love and cherish her everyday. Her marriage was over and Derek had made it clear to her today that he was bright and shiny without her and had well and truly moved on with Meredith and now it was time for Addison to do the same. She wipes the tears from her face and when she turns around she spots Derek on the upper deck of the ferry and he is looking straight at her. Just my luck Addison thought, well he wanted her to take of the rings this morning when he realised she still had them on, he had even joked to her about soap being nice and slippery. Like he didn't care less that those rings had once meant so much to them both.
Addison catches his gaze for a moment and is surprised to see that there was actually some emotion towards her in his face rather than the usual indifference. She looks away trying not to give him the satisfaction of seeing her crying over him and she walks away to the other side of the ferry.
A couple of minutes later she heard him clearing his throat before saying her name. "Addison."
"Just leave me alone, Derek. Can't you see that I'm still hurting. You got what you wanted. You're free from Satan and you and Meredith are bright and shiny, so just leave me alone. You said you never wanted to see me again, so just stop rubbing my face in your happy life."
"I'm sorry Addie, I shouldn't have been so insensitive and I'm sorry if I pushed you to get rid of the rings. They were yours and you should have kept them if you wanted too."
"It was time for me to let go. If I held onto them then I'm not sure I'd have been able to move on. I need to move on, Derek so just leave me alone to do that. Please, that's all I ask. If you ever loved me, the way I loved you. Then you wouldn't rub it in my face."
"I'm sorry Addison, I promise I'll leave you alone if that's what you want and I promise I will be more discreet with Meredith from now on. What I said the other day, about not wanting to see you again. I didn't mean it Addison I was angry and I lashed out. I did love you Addie, don't ever think that I didn't. I just couldn't help my feelings for Meredith and it was never the same after what happened with Mark. I'm so sorry if I gave you false hope. I thought that I owed it to us to give it a try and I'm sorry, I'll leave you alone now."
"Thanks Derek, maybe in time we could be friends again but right now I'm still getting over it."
"I'd like that. Take as long as you need. I'd like it if eventually we could get on and be friends but I understand if you can't do that. Goodnight Addison."
"Goodnight Derek."
As Addison watches Derek walk away she feels like she is starting to get some closure and now it is time to rebuild her life. She may have lost the love of her life, but she was still an amazing surgeon and she would survive. It was time to let go of the past and concentrate on the future.
