Firstly, I must say that the premise for this story came from a youtube video. MommyToBe. I'm using some of the story idea, but changing it up a bit to fit my ideas.

Still working on my other story, but a bit of writers block has me stuck for now.

Definitely AU.

Cast of Characters:

Katherine "Kate" Beckett- Tough New York Detective. Recently separated from her husband of three years.

Richard Castle- Best selling crime author. He's madly in love with Kate, but since she is married, he doesn't act on those feelings. Simply content to be her best friend and partner.

Alexis Castle- I have made her younger for the purposes of this story. In my story she is six years old. Just as precocious, but her parents divorce and being abandoned by her mother has had a terrible effect on the young girl.

Martha Rodgers- Castle's mother and grandmother to Alexis. She is eccentric and loveable. Always good for a laugh. Very protective of Castle and Alexis.

And because I like him, Roy Montgomery is alive and well in my story. Along with the usual cast of characters. Lanie, Ryan and Esposito will definitely be a big part of the story.

Lanie Parish sat in the woman's restroom and waited for her friend to show herself. When she did, she looked ashamed and shook her head, "I don't want to talk about it Lanie."

Shaking her head she told her friend, "Yeah, you've said it often enough over the past three days." Feeling her friends forehead, she continued, "You don't have a fever so that rules out the flu or food poisoning. Your eyes are clear. So, I don't think there's anything wrong with you. And yet you keep getting sick. Numerous times a day."

"I'm fine Lanie. I..."

Lanie crossed her arms in front of her and gave her a look that told Kate she didn't believe her, "Girl, you can lie to a lot of people here. You can lie to Espo and Ryan. Hell, you can even lie to Castle, but you can't lie to me. Tell me what's wrong with you."

Kate didn't want to tell her best friend what was wrong. It was bad enough that she had put her self in this position, but the tell someone else would make it that much worse. She shook her head, "I can't Lanie. I..."

Lanie sighed, "I'm your best friend. What is wrong with you sweetie? First you and Josh separate and now you're getting sick. Please tell me..."

Kate simply shook her head and Lanie saw the tears shining there. Lanie watched as her friend pushed past her and walked out of the bathroom. Leaving a confused Lanie standing by herself.

Kate went into the break room to get a cup of coffee. It probably wasn't good for her, but she didn't care right then. She needed something to calm her nerves and coffee would do that for her.

She watched as her coffee brewed and thought back on the events of the past month.

She and Josh had been so happy together. They married after a whirlwind romance. They had been married for nearly three years. They never argued. Except about one small thing. Kate wanted a family. She wanted children. Josh didn't. He wanted to be free to go off on his trips around the world. He didn't want to have to worry about the time and expense that children would bring into his life.

So, when Kate missed her first period six weeks ago, she knew that she was pregnant. She had always been regular and could count on her period coming like clockwork. So, she had taken a pregnancy test and for a brief moment, she had been excited. However, all that changed when she told Josh about the baby.

The look he gave her was one of contempt. Then he asked, "Are you going to get rid of it?"

Kate had been horrified at the suggestion. Even if it wasn't a planned pregnancy, she couldn't imagine getting rid of their baby. He or she was a product of the love that they shared. She finally told him, "No. I want the baby."

He swallowed hard, "You want the baby. You want it more than you want me."

Shaking her head, Kate whispered, "No. I love you."

"Then you will do the right thing. The sensible thing."

"I can't... I..."

"Listen Kate, it's very simple. You have to choose. It's me or that thing that you are carrying. You can't have us both."

Putting her hand on her stomach, Kate shook her head, "I can't Josh. Look, it's all a big shock, I'm sure in time you will grow to love this baby and..."

Josh simply shook his head and told her, "No Kate. I won't grow to love it. I've never wanted kids and you knew that. You agreed that we weren't going to have children. You betrayed me Kate. So, you have to do the right thing and take care of it."

"Why? Because you say that it's the right thing! What if I want this baby?"

"Then you will lose me. It's one or the other Kate. You can't have both."

Kate could only stand there in shock. She couldn't believe that the man that she loved with her whole heart would talk to her like this. When she didn't answer him immediately, she watched as he shook his head and left the room. She heard him slam a door somewhere in the house. After a few minutes, he reappeared in the kitchen and told her, "I'll get the rest of my clothes when you're at work. Don't bother calling me." He turned to leave, but turned back around and told her, "Unless you get rid of it. Then I will forget all about your betrayal and I will gladly take you back. However, if you don't get rid of it, I will have no choice."

"What are you talking about? What choice don't you have?

He shrugged, "I will divorce you."

Kate was shocked. How on earth could a baby make him mad enough to leave her? She had to have been dreaming. She would wake up and Josh would tell her how happy he was about the baby and everything would be back to normal.

However, she knew that it wasn't a dream when she woke the following morning and saw that Josh's side of the bed hadn't been slept in and a some of his clothes were missing from his side of the closet. She sighed sadly and got ready for work that day.

She knew that she should have stayed home that day. She had snapped at everyone and everything got on her nerves. Especially Castle and his damn theories. She had finally looked at him and snapped, "Would you please shut up? No one wants to hear your theories all the time."

The others had gotten so quiet that you could have heard a pin drop. Kate was horrified at her behavior. So, she grabbed her coat and hurried out of the station. Ignoring Castle as he called for her to wait for him.

Once she was out of the precinct, she slumped up against the wall and she let the tears fall. How had her life fallen apart in the span of a day?

When she got home, she noticed that her house had been cleaned out. He had taken every piece of furniture that they had bought. The only thing he had left her was their wedding album. Which she picked up and hurled across the room. Then she slumped down the wall and fell apart.

She had been debating about whether or not to do as Josh asked. She loved him and she could have him back very easily. All she had to do was get rid of the baby. It was a very simple procedure. It could be done easily in her doctors office.

So, she made an appointment with her doctor the morning after Josh left. She wanted to talk to him and get the pregnancy confirmed. She also wanted to find out about possibly terminating the pregnancy. She loved Josh and wanted him in her life. Even if it meant getting rid of the baby that she carried inside her.

Kate had always loved her doctor. He was a wonderful man. He had always been like a father to him. When he walked into the room, he smiled at her and said, "So Kate! I hear that you think you might be having a baby."

Kate could only nod and say, "Yes."

Doctor Taylor was a smart man. He'd been delivering babies for longer than Kate had been alive. He knew how to read people and Kate was no different. So, he asked her softly, "What's wrong?"

Watching her closely, he saw her swipe at her eyes and she whispered softly, "My husband doesn't want the baby."

"Why not? Is there some kind of disease in the family that he's afraid of?"

Kate shook her head, "No. He's never wanted kids. And I didn't think I did..." She sighed and then she continued, "At least until I took the pregnancy test. Now however...I want the baby..."

"But?"

"But I don't want to lose my husband. I want to talk about terminating the pregnancy. I..."

Doctor Taylor looked at his patient and smiled sadly. He could tell that she didn't want to get rid of the baby that she carried. He hadn't been delivering babies for forty years for nothing. He could tell women who were serious about having an abortion and someone like Kate. Someone that felt trapped between the man she loved and the baby she carried.

He smiled at Kate and said, "Well, lets determine if you are indeed pregnant or not."

He handed her a cup and pointed towards the bathroom. Once that was done, her performed the test and smiled at her, "You are pregnant. If you can lay down I want to perform an exam and listen for the heartbeat."

Kate nodded and laid down on the table. She closed her eyes and cried silently. Part of her wanted this over and part of her hated Josh for putting her in this position. For making her choose between him or the baby she was now carrying. She thought it would be easy. That she would go in and the doctor could give her a pill to take and it would all be over. She sighed and wished that she was home in bed. At least there she could cry in private.

After a few minutes, she heard a soft swooshing sound fill the room. Her eyes popped open and she asked, "What's that?"

Doctor Taylor smiled, "That's your baby's heartbeat."

It was at that moment that her heart melted and she whispered softly, "My baby? It sounds very fast."

He smiled and nodded, "It's completely normal. One hundred and thirty beats per minute. Now, since you want to terminate the pregnancy, I need to explain the procedure to you."

Kate walked out of the doctors office and the sun hit her in the face. She decided that she needed to call and tell Josh the news.

When he answered the phone he didn't say hello. All he said was, "Did you do the right thing?"

"I couldn't do it. I heard the baby's heartbeat and..."

"You decided to keep the thing then."

"Yes Josh."

"So, you made your decision then."

"Yes. I'm sorry. I still love you."

Josh laughed harshly and said, "No you don't. Otherwise, you would have gotten rid of it. Do me a favor Kate."

"Anything."

"Don't call me again. Any communication that we have will be through our lawyers."

With that, he hung up the phone and Kate dissolved into tears...

Now I realize that not everyone is going to like this story. Some people are probably against any baby that isn't Castle's. I think it's an interesting premise and decided to explore how Castle would react to Kate having a baby that isn't his.
