Ok I did post earlier today but since you guys are so loyal and I have some time on my hands, I'm gonna post another chapter for you! Enjoy!

XXXXXXXXXX

Derek looked into her blue-gray eyes, trying to find the lie he knew was in there somewhere. She was hurt and was lashing out, trying to hurt him the way he had hurt her. And he couldn't blame her. He watched intently as the lie showed itself: she placed her head in her lap, her fingers intertwined behind her neck, breathing slow and staggered from under her curtain of hair.

"I'm sorry. I don't know why I said that," she said, tilting her head sideways so she could see his face. It was covered in fear. "Of course it's not true," she said quickly yet honestly. The fear dispersed, replaced immediately with relief.

"Why would you say that?" he asked quietly. She had scared the living daylights out of him.

"I'm sorry," she said equally as quietly. "I was mad at you. I just wanted you to feel pain. And judging by the look on your face I did just that," she said, finding it impossible to keep a small grin off her face. He grinned a little back at her, though not enough to say that he was no longer upset. Both the smiles fell from their faces and they slipped into an uncomfortable silence.

"What are you doing here?" he said finally. "In Boston, in this apartment. Without me," he said.

This time she didn't look into his face. She simply removed her head from her lap and leant back so she was leaning against the back of the couch.

"You're married. And I'm your pregnant mistress. Those two things don't really go hand in hand," she said logically.

"Meredith you know that you were more than just my mistress. We had something special."

"And that's why I left."

"What? What's why you left," he asked, confused at what she was saying. It felt like she was speaking in riddles today.

"Past tense."

"I ... I don't follow."

"You said we had something. Past tense meaning we don't have it anymore."

"Meredith come on! You're going to cut me out of our daughter's life because I used bad grammar? You're smarter than that! And I know that you don't want out daughter to grow up without a father the way you did. So why would you put her through that knowing what the end result is going to be!" Derek asked, his voice starting off as a whisper but ending up a heightened plea. "I know that you're angry at me but don't make our daughter suffer for it. This is our mistake, not hers. I want her to come into this world as innocent as she is right now. I don't want to burden her with this.

"Meredith don't you understand! This is going to be my only shot at having a child. Addison and I, not only can we not have kids, but we would be the worse parents ever! I think that Addison likes the title of a mother more than she would like motherhood itself. Out poor kid would grow up alone, both its parents at work all the time. I don't wanna do that to any child of mine. At least having a baby with you I know that the baby's gonna having at least one parent who'll always be there for it. And two if the mother lets up," he added with a slight smirk.

But she didn't smile back. "Derek it's not like I don't want you in her life. It's just that I don't want to make the wrong choice. And I know that maybe cutting you out of her life wasn't the best possible choice for all three of us. But I want you to know that from now on, everything I do I do because of her. She comes first no matter what. And you ay not respect some of the decisions I make when it comes to her but ..."

She let the rest of her sentence hang in the air. But Derek didn't need her to finish; he had gotten the gist of it. And as they sat there in silence, he watched as she completely broke down. Her head went back into her hands as she started to cry. At first Derek was taken aback but then he regained his composure and comforted her.

"Mer hey," he said soothingly. His hands on either side of her torso, he arched her back so her wasn't staring into her lap and was now looking into his face.

"It's gonna be ok. I promise. This is all going to work out," he said. But she continued to sob. He pulled her into his chest so her head was resting on his shoulder, her tears dripping onto his shirt. "We're gonna do this. Together. And we're gonna do it right."
