A/N: Just an idea I had. I hate Derek; I think he's a jerk, except when he's truly happy with Addison. I like Addison, and always end up feeling horrible for her because of what Derek did.

AU, back in Addison/Derek's 10th year of marriage. No Seattle, no Meredith, no affair, just Addison and Derek trying to work things out. Derek's a jerk. Oh wait, that's just normal.

Addison was rarely giddy. Years of studying and being mocked had caused her to miss the teenage years when all she should've cared about was wearing the right lip gloss or dating the right guy. When she should've been giddy. Derek had once jokingly told her she didn't know how. It might be true.

But walking onto Derek's floor Addison was giddy. Like someone who just got her first kiss. She and Derek had been in difficult times lately, but hopefully, this would change it all. Hopefully this would change his opinion and maybe he'd come home more than once a week.

She found him making his rounds, and pulled him off into a room.

"Jesus, Addison, what?"

Addison pulled the papers out of her bag. The pictures. Derek looked down at them. "You're, pregnant."

"Yes." Addison smiled.

"But, we can't have a baby. I'm getting at the top of my game right now. This isn't good. Oh my God. This isn't good."

Addison's face fell. But Derek was too preoccupied with his thoughts to notice.

Derek eyes flicked upward, meeting with hers. "When did you go off the pill?"

"Two months. I told you that. Remember? We decided that we would try. We're getting older and older, Derek. Don't you remember at all?"

Derek shook his head. "Can't you have an abortion?"

Addison felt the tears hiding behind her eyes leak out. "Derek, it's our child you're talking about. Our baby."

"It's just a fertilized egg. Just an egg, Addie. Maybe we can have a baby in a couple years."

"Derek, you said that a couple years ago. And a few years before that. I'm sick of waiting. I want a baby. But I've been on the pill for years. And I've wanted a baby. I'm a freaking OBGYN, for God's sakes. Do you think I'm one because I hate babies? Do you?"

Derek walked out of the room. Addison slid down against the wall and felt her composure crumble. He didn't want his own baby. He wanted her to abort the baby. Addison wasn't going to. Even if it meant, even if Derek didn't support her, even if Derek left her, or if she had to leave him. She was having this baby.

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

Mark heard sobbing coming from a room to his left. It sounded so familiar, almost like…Addison. He opened the door and saw her red hair, crumpled.

"Addie, what's wrong?" He walked over toward her, preparing for the worst.

"I." She breathed deeply, regaining air. "I, I'm pregnant."

"Why, Addison, that's great! Why are you crying?"

"Derek doesn't think so."

"What do you mean?"

"He…he…he wants me to get an abortion."

"Don't, Addison, don't. He's just having an off day."

"Don't defend him. He's different and you know it."

Mark sat there next to Addison and nodded. He knew it was true. And it hurt that it was.

A/N: More a prologue than anything. Derek's an ass. Oh well, that's just how live works. (I'm very bitter towards Derek, he's an indecisive jerk who leads everyone on.)
