Derek turned away to face Burke; a feeling of anger began to wash over him.

'I swear to god I'm going to kill her.' Burke didn't have a clue over what Derek was talking about until her turned to face the door. Taking a double look at who it was he put his drink down and walked over to the door.

'I don't think you two should be here,'

'Burke, butt out, this has nothing to do with you,'

'Wrong Addison, it has everything to do with me. You being here is only going to cause trouble and you hurt him, and the fact is he is my college and I wont have you upsetting tonight, now will you please leave?' Mark came round and stood in front of Addison, in a protective manner.

'Dr Burke, we are looking for Derek, let us see him and there won't be trouble,'

' Mark, I don't care what you want, but I am telling you to leave now, before I call security,'

'Mark leave it, I'll catch him some other time,' Addison took hold of his hand and lead him out of the large room, leaving Burke feeling very macho. Christina came up and put her arms around Burkes waist.

'Forget him and come and have a drink with me,' Burke followed Christina, not noticing that Derek had left the ballroom.

Meredith took a drink of the beer, hoping it would give her courage. It was 18 degrees outside but she wasn't cold. Leaning back on her heels she heard the door creak open.

'What took you?'

'I had a small matter of my ex-wife to deal with, well Burke did anyway,' Derek looked to the ground and smiled, thinking of Addison's reaction to what Burke had said.

' I want to talk to you, but I didn't want to have everyone watching as I did,' Meredith walked over and took Derek's hand, pulling him over to the side of the building.

'Yesterday, I was in tears lying on my kitchen floor with Izzie and George having to put me to bed because of you,' Meredith took a deep breath in before continuing.

'You broke my heart and it still hurts. I was your second best…'

'Meredith I…'

'Derek, shut up and let me finish. I felt like I had been hit by a ten tone truck and it was all because she came back and messed up everything. You had the choice to sign the divorce papers before you caught her and Mark again and you didn't.' Meredith turned and looked at Derek.

'You can't expect me to just get back with you because Addison screwed Mark again. It was only when she hurt you that you came back to me. That's not fair. When I was getting ready tonight before I arrived I needed time to think things over and I feel so weak when I do this but…' Meredith pulled Derek in towards her face and kissed him.

'I still love you and can't help the way I feel. But you hurt me really badly and I hate you for it, but I can't stop loving you and I hate the fact I can't stop loving you,' A tear fell from Meredith face.

'Meredith, you were never my second best. I was married to Addison for eleven years and I owed it to our marriage, even though it was a shambles to at least try. Every day I was with her I missed you and regretted what I had done. I didn't love Addison and she clearly doesn't love me. But it took her screwing Mark for me to see how much I need you and want you to let me love you.' Derek Pulled Meredith in and embraced her so tightly. He didn't want to let her go ever again and he felt like and ass for doing it before. Derek took his jacket off and put it over her shoulders. They stood looking over the skyline of Seattle, holding each other when the door opened.

'You don't give up do you?' Meredith slipped Derek jacket of her shoulders and handed it back to him as she walked over to the door, rage seething through her veins.

'Derek, I just want to talk to you for a couple of minutes to explain what happened,'

'Satan, what is your problem? Are you not happy if he's happy for once?'

'Meredith, this has nothing to do with you,'

'Really, is that why you punched me earlier? I have nothing to do with this but you'll still punch me? That makes sense,'

'Meredith please…'

'No Addison, I'm sick of you getting your own way,' Meredith slapped Addison across the face.

'Call us even,' Derek walked over and put his hands on Meredith's arms. Shrugging his hands off, Meredith went through the door, leaving Derek on the roof with Addison.

'Addison, just go, I don't want to hear it,' Derek followed Meredith through the door leaving Addison on her own, to finally fall apart.
