8. Kate gets worried that Castle may be losing interest.

The first time it happened Beckett didn't think much of it they didn't need to spend every waking minute together right? She had already moved into the loft months before so there was no need to be feeling insecure about the relationship. So what if he cancelled one date it wasn't a big deal.

The second time he cancelled on her she still didn't think much of it, there was no need to panic it wasn't like she hadn't cancelled on him before. But there was still everything in between all of these cancelled dates that were starting to make her wonder.

It was late one night when she returned home from the precinct expecting to find Castle home but he wasn't. She had sent him a text which he hadn't replied to and tried to call but he hadn't picked up. When he got back and she had asked where he had been he claimed to have been taking a walk to clear his head.

The next time that she returned home late he was on the phone, he obviously hadn't heard her come in since he was on the phone when she walked into his office. He quickly made the excuse of saying that he would call back later in the week. She tried to play it off that it was a call with Gina or Paula but she could only think of that for so long.

He skipped out on her a couple of days after that claiming to be going to a meeting with Paula about the publicity of the new book but she knew that he had one scheduled for the week after that. She tried to play it down but she was slowly getting the feeling that Castle was pulling away from her. She was trying her hardest to make this relationship work because she knew that he was her "one and done" but her heart was slowly starting to feel like it was breaking.

It was later that same week that Castle had come home to find Beckett sitting on the couch. She was sat at the corner her knees up to her chest and she tried not to let the tears escape.

"Kate?" He went and sat next to her and placed his hand on her knee but she flinched. "What's wrong?"

She didn't look up just kept her head down trying even harder not to cry in front of him.

"Kate?" Castle tried again. He moved his finger until he could lift her chin up and look at her.

When she saw the concern in his eyes she let a tear roll down her cheek, he wiped it away with his thumb before another one escaped.

"Castle…Rick." She got out. "Are you trying to break up with me?"

"What why would you even think that?" He asked looking at her like she had gone crazy.

"These past couple of months it feels like you've been distant. I don't want to lose you Rick." She said

He took a deep breath before realising what he had to do. "Kate." He waited for her to look at him before he moved to take her hand. "The reason I've been go so much lately is well…" He paused and reached into his pocket before getting down on one knee in front of her. Her eyes widened as she realised what he was doing. "Kate will you marry me?"

She stared at him for a second sniffling before a smile came onto her face. "Yes." She said quietly. "Yes I will."
