Disclaimer: I own nothing.

This is a story about Mark and Addison Sloan. Addison never left to go to LA, she never slept with Alex and Mark didn't break the bet. I told myself that I wasn't going to start another fanfic, but I bought the complete fourth season and just got down watching it. So here I am, Mark and Addison are my favorite Grey's couple (Even though their not actually a couple) So I'm writing a new story about them:]

Summery: Mark and Addison Sloan have been married for four years. They have a Beautiful house, nice cars, jobs that they love, all the money they need, and great friends. But something is missing, something that Addison has always wanted and something that Mark thought he never wanted. A baby. What happen when the pregnancy happens to be very high risk and could possibly kill Addison and the baby?

Chapter One: This can't go on forever.

Addison Sloan sat on the edge of her bathtub looking at yet another negative pregnancy test. She and Mark had been trying to have a baby for over a year now and nothing had happened, every test was negative. No two lines, Just one. One line.

"Addie?" Mark said walking into their master bedroom.

"In…here." She said wiping the tears from her eyes.

"What are you-" Was all he got out of his mouth before seeing the test in her hand.

Addison tried to hold back her tears, but couldn't. She looked up at Mark with tears rolling down her cheeks.

"Addison." He said wrapping her arms around her, hugging her tight. "Shh, its alright."

"No, its not alright." She cried into his jacket.

"This cant go on forever." He whispered.

Addison didn't say a word, she just cried more into his jacket. "What's wrong with me?" She finally spoke.

"Nothing is wrong with you, your perfect." He said picking her up, just like he did when they got married. He carried her over to their king sized bed.

"No, Mark! I'm not perfect, if I was perfect we would have five freaking babies by now!" She snapped snuggling under the covers.

"Addison, we could always adopt? That's an option." He said softly.

"That could take years, I wont a our baby."

Mark just sat on the edge of the bed looking down at the hardwood floors.

"I'm sorry I snapped at you." Addison said sitting up and putting her hand on his back.

"It's okay, I no your just frustrated." He kissed her.

"How about we make a deal?" She smiled.

"What is it?" Mark smiled back.

"We try one more time for a our baby and if it happens again, then we'll look into adoption."

Mark smiled. "Okay, it's a deal. But please Addison, don't get your hopes up okay?"

"I'll try." She smiled because she didn't really know how not to get your hopes up. It was their baby, a mixture of her and Mark in a tiny little package.

It was a few days later, Mark came around the corner on the fourth floor. He saw Addison through the window of the hospital nursery. She was holding a little baby wrapped in a pink blanket, from what he could see Addison was trying to get the baby to stop crying. He saw her rock it back and forth, until it fell asleep.

"Hey." She said walking out into the hallway.

"Hey." He said giving her a kiss.

"You know what tonight it don't you?" Addison smiled big.

"Addison, your getting your hopes up." He sighed.

"Baby night!" She smiled even bigger.

"Addison." He said again.

"Mark, this time is different. I know it, I can feel it." She said.

"I just don't want you to be disappointed."

"Did you hear what I said…I have a feeling, a good feeling." She smiled right before her pager went off. "I got to go, but I'll see you later tonight."

"Okay, see you tonight." Was all he said because he didn't want to argue about a feeling that she had.

Later that night Addison pulled into her driveway, looking at the clock and seeing that she had only an hour before Mark got home.

She hurried inside and into the kitchen, so she could pull out the chocolate strawberries that she made that morning and a bottle of champagne out of the fridge.

Addison ran the water in their master bathtub and poured almost a whole bottle of bubbles in the tub. She placed the strawberries on a trey with two empty glasses for their champagne.

While the water was filling up, Addison ran a brush threw her hair and applied some red lipstick to her lips.

Mark got home a little earlier than Addison had expected. Hearing the door open and then him calling up the stairs.

"Hey babe, I'm home."

She took off all of her clothes, until she was only wearing her red pumps. Right before he walked into the room, she thought to herself. God I hope this works, it has to work. This is the last chance. This cant go on forever.
