A/N- Thanks for all the good reviews. I am glad you all are enjoying it so far. Well here is another chapter.

"I'm pregnant."

Derek stood in shock. He had no clue as to what to say. "Are you sure?"

"No Derek, I just have a degree in Obstetrics, but I'm not sure if I am pregnant. Yes I am sure!" She yelled.

"Don't yell at me Addison!"

"Don't tell me what to do! I am not your wife!"

"Yeah you have made that perfectly clear." He said bitterly.

Addison stared at him harshly. "Yeah well you made it pretty clear to me the day you chose her over me!"

"Addison we both agreed that the marriage was over. It was a mutual decision."

"I am not talking about that Derek I am talking about before."

Derek stood flustered. "What before Addison? Before that I had chosen you!"

"You stayed with me physically, but you hadn't chosen me. You chose her and you know it! You couldn't have both of us Derek! You couldn't have both of us, so you decided to go for the newer woman." Addison was angry and it showed in her mannerisms.

"I chose you Addi, I was with you!"

"You haven't been with me since before Mark! You were there when you wanted to be and you were only there with what was left of me. Those last few years had drained me so that all I was was a shell of my former self. You…" She didn't know what else to say and she was so angry she was having a hard time forming coherent sentences.

"Are you blaming me for Mark? You better not be Addison! I am not the one who had an affair; there was no other woman!"

"Yes there was!"

"Who?"

"Your work; your work was more important to you than anything else. It took president to everything in your life." Addison looked down. She was tired; tired of fighting a battle she knew she couldn't win. "Derek just leave."

"Addison we are not done." He said forcefully.

Her head whipped up. Her eyes burned with fury. "Oh yes we are." She annunciated every word with great force.

Derek nodded and turned around. "Addi…"

"Just go." She said softly.

Derek did as she asked and left the apartment feeling empty and like a worthless man. Addison sat down on her couch and curled up resting her chin on her knees. Slowly the tears began to fall. Right at that moment she would have given anything for a drink.

-2 Days Later- SGH-

Addison sat in her office and stared at the computer screen. She hadn't talked to Derek since the night at her apartment, and she felt miserable. She just wished she had the guts to apologize, or that he would say he was sorry. She hated not talking to him and always felt alone when they were not talking. Addison took a deep breath and slowly let it out. She slowly removed a blank sheet of paper and a pen. If he was not going to take the first step, then she would.

-Same Day- Dr. Morris' Office-

Derek walked into the psychiatrist's office and sat down in the plush chair. "So Derek what brings you in today?"

Dr. Morris was one of the doctors that Derek had seen when he had first arrived in Seattle. It had been a while since he had seen him, but without Addison to talk to he had to turn to the doctor. "I had a fight with Addison."

"You two are divorced now right?" The doctor asked as he pulled out his pen and pad.

"Yes, we have been for a little while now." Derek ran a hand through his hair.

"So what was the argument about?"

"Well, you see about two months ago I took Addison with me to New York for this gala that I had to attend. I wanted to take Meredith, but she refused to go, so I took Addi. Anyway we got drunk one night and had sex. We both agreed not to mention what had happened that night, but now we will not be able to cover it up."

"Why not?"

"Because Addison is pregnant. That is what she told me last night, and we started arguing, but the thing was we weren't arguing about the baby, but about the past."

"Did you two ever talk about the past?"

"Well we talked about the good stuff, but we didn't really talk about the affair." Derek looked out the window and sighed. "Last night I suddenly got this overwhelming urge to ask Meredith to marry me, and I don't know why."

"Derek you know why, but you don't want to admit that you know why." Derek sat and absorbed his words. He did know why, and the reason scared him. "Now why did you want to ask her?"

"Because I am afraid that if I don't that I will…that I…that I will fall for Addison again. I mean she is carrying my baby, our child. I don't know what to do."

The doctor sat and listened carefully. "Well tell me something. Are Meredith and Addison anything alike?"

Derek chuckled dryly. "No, not at all."

"So they are complete opposites." Derek nodded. "Then why are you with Meredith?"

"What do you mean?"

"You married Addison and thought she was the 'love of your life' until she had the affair. One would think that the next wife would have some similar qualities as the past wife, but you say they are completely different. To me it seems as if you only love one woman and that the other is just there to fill the void the other has left behind."

Derek sat and stared out the window. Was Meredith just a filler? Or did he really love her? He looked down at his watch and saw it was time for him to leave. "Thank you doctor Morris, but I have to go." He slowly stood and turned to leave.

"Derek, even if you don't love Addison you still need to be with her during the pregnancy. Don't let her do it alone, or you will hate yourself for forever. And tell Meredith the truth; don't let her wander around in the dark."

Derek nodded and left to go to work. All day Derek could only think of one thing, that he was going to be a father.

-That Night- Addison's Apartment-

Derek took out his key and opened her door. He had to talk to her and knew that if he knocked she probably would not let him in. "Addison! Addison I need to talk to you." He yelled throughout the apartment.

She came running out of the bedroom in a tank top and a pair of shorts. "What are you doing here?"

"I'm sorry. I am sorry about New York, I am sorry about last night, I am sorry I was a bad husband, mostly I am sorry that I was never there for you when you needed me, but I am here now. I want to be there to support you and the baby. This doesn't mean we are back together, because we will never be there again, but I want to be a good father to our child, and I want to be a great friend to its mother." Derek slowly walked towards her and placed a hand on her face. A few tears were threatening to overflow, but she held them back. A smile broke out across his face. "I am going to be a daddy. And even though it is not a convenient time or the right circumstances I am still happy. Addison I love you, and I promise to help you any way I can."

"What about Meredith?"

"I will tell her, in time."

"We are going to have a baby." She said as a smile graced her face.

"We are going to have a baby." He reaffirmed. Derek smiled and pulled her to him holding her close. He was ecstatic about becoming a father, but scared at the same time. He didn't know how he was to tell Meredith, or what he would do once the baby was born. All he knew was that he would take advantage of the time he would get to spend with Addison one on one. He knew deep down that he would never love another woman the way loved her, and that he would never truly stop loving her. Having a baby with her was only going to make that love stronger and the pain of losing her deeper.

-5 Days Later-SGH-

Derek pulled out his Blackberry and looked down to see if he had any messages. He had one in his inbox that was from Meredith.

Hey,

Can't make it to dinner tonight, sorry. A surgery just came up. Ttyl.

Mer

Derek sighed and leaned up against the railing. He had planned on telling her about the baby that night, but now he was going to have to find another time to do that. He had planned on making her a fancy dinner and then telling her, but now he would have to eat the food on his own. Or would he? He checked to see if Addi was on and sent her a message.

To:dr.Satan

Hey Ad get on your im. I need to talk to you

From:DrMcdreme

Derek walked to the cafeteria and sat down waiting on her response. He saw her screen name come up and began to talk to her.

dr.Satan: Hey what's up?

DrMcdreme: I have a proposition to make.

dr.Satan: Okay shoot.

DrMcdreme: Have dinner with me tonight? We could meet at the apartment…Mer and I only have a table, couch, and T.V., but hey it is better than the trailer. LOL

dr.Satan: LOL…where is Mer? Wait…working…weren't you going to tell her about the baby tonight?

Dr.Mcdreme: Yep, on both accounts. But now I am going to be eating alone, unless you agree to come eat with me?

dr.Satan: Well since you sound so desperate, I guess I will. See you at eight?

Dr.Mcdreme: Thanks, and eight sounds great. Hey that rhymed…LOL…

dr.Satan: Shut up and get back to work…I will see you at eight. Bye

Dr.Mcdreme: Okay…bye.

Derek shut his Blackberry off and went back to work eagerly anticipating the evening to come.

-1:00 am- Derek and Meredith's New Apartment-

Meredith walked into the apartment and placed her bag down in the hall. She walked into the kitchen and could smell something different. She opened the refrigerator and found a round Tupperware dish with a post-it note attached to it.

Mer,

Left over dinner. Hope you enjoy.

Derek

She pulled the lid off and popped it in the microwave. She looked down in the sink and saw too many dishes; she knew Derek could not use that many dishes. She walked into the living room and sat down with her food. She looked over and saw Derek's Blackberry beeping. She picked it up and looked down. She opened the message and read: "Hey Der, thanks so much for the great dinner. Good luck with telling Meredith, and I really enjoyed our conversation today…LOL. Well I will talk to you tomorrow. Love ya, Addi." Meredith's blood boiled as she heard her voice read the message out loud. She wanted to know about this "conversation" that Derek and Addison had had. She went through his saved conversations and found it. She became furious when she read it. Then she went back over it and read the line about the baby. What baby? Was Addison pregnant? Whose baby was it? Was it Derek's? It couldn't be his, could it? Meredith stormed into the bedroom and flipped on the light. "Is it yours?" she yelled.

Derek sat up groggily and squinted. "What are you talking about?"

"Is the baby yours?" She asked again.

Derek stood and looked at her solemnly. "Yes."

A/N- Okay so I am sorry that I ended it there, but you will have to review, and then find out what Meredith is going to say. Trust me all hell breaks loose next chapter.
