A/N: Hey guys! I got like, no reviews for my last chapter, and that makes me sad :( But here's the jealous Fitz that some of you were asking for! I hope that you enjoy and that you review this chapter! I'm really caught on what the gender of Mellie and Fitz's baby should be, so I'm definitely wanting suggestions on that. As well as name suggestions! And as I said in previous chapters, I want to know what y'all want to happen and what you want to read about! So let me know! Happy reading:)

The next time he saw his wife, she was chatting with Andrew in the hallway. He wasn't exactly sure why, but he felt a surge of jealousy when he saw them. Of course, he knew that there wasn't anything going on between them. But it still gave him butterflies in his stomach when he saw the two of them together, when he saw Mellie laughing and smiling and giggling as he spoke to her. He couldn't help it. He couldn't help thinking that there was something going on, even though he knew that there wasn't.

Fitz turned to talk to Cyrus for a total of thirty seconds, and when he turned back around, Mellie and Andrew were slipping into Andrew's office. He raised an eyebrow, a bit unsure why they had to continue their conversation in private. Deciding to distract himself so that he didn't get angry, he found his way down to the kitchen to get something to eat. On his way back up to the Oval Office, he ran into Mellie, who was sneaking out of Andrew's office, looking very suspicious, much like a teenager sneaking out of her boyfriend's window in the middle of the night. When she saw who she had walked into, her eyes widened, and she looked like a deer caught in the headlights.

"Fitz, it's not-" She immediately tried to stand up for herself, which made Fitz even more suspicious than he was already. This was getting awfully weird, and he wasn't exactly sure what to think. "It's not what you think."

Fitz raised an eyebrow, continuing to stare at her. "It's not what I think? What do I think, Mellie?"

Mellie sighed, looking at him. This was definitely not going well. "Fitz, I mean it's..." She let out another small sigh and decided to try again. "I'm sure that you think that there was something inappropriate going on."

"That's not what I think, Mellie. You think that I'm that insecure? So insecure that I would think that just because my wife and her ex-boyfriend, whom she cheated on me with, were in the same room with the door closed that she has to be fucking him? I'm not that insecure, Mellie. I actually trust you." Of course this wasn't true, but he had some strange urge to be an ass about the situation.

"Fitz, I...I'm sorry, okay? I just know that you don't like when I'm alone with Andrew and I was just trying to assure you that nothing was going on."

"If you know that I don't like it when you're alone with Andrew, then why in the hell were you alone with him? Why did you go behind my back and do the one fucking thing that you know I don't like you doing?" He was making a scene right now, but he honestly didn't care.

This was ridiculous. This was absolutely ridiculous and hypocritical. "Why did you go behind my back to be with Olivia Pope the other day? You know how I feel about her. You know how I get when you go to see her, when you sneak out and go to her house. I wasn't angry with you when you told me that you were going to see her, why do you have any right to be angry with me now?"

Fitz chuckled to himself, shaking his head. "Do you not get it, Mellie? It's not the same. I had a reason to be talking to Olivia. I told you before I went to speak with Olivia. You knew I was with her. I had to find out that you were with Andrew by walking down the hallway and seeing you sneaking out of his office. You had no reason to be with him. And I know exactly why you were with him, actually."

"Are you stupid?" Mellie asks, and Fitz is completely and utterly shocked. "I was just with you. I just screwed you on your desk, in your office, less than an hour ago. Why in the hell would I be going to Andrew to get more? Do you really think I'm that much of a whore? Do you really think that I can't stay faithful to my husband? Do you really think that I don't think sex from my husband is enough and that I have to go get finished off by Andrew? Fitz, I had a reason to be there. I can't tell you what it is, but I had a damn good reason to be there. And I can assure you that I kept my clothes on the entire time that I was in his office." She wasn't sure why she felt the need to explain herself to him. She was beyond angry at the fact that he didn't believe that she wasn't having sex with Andrew. How dare he even think that?

"Your clothes were on, but were his?" He knew that was a low blow. He knew that that was uncalled for and completely inappropriate, but he was angry and they were fighting. If she had reasons to have been alone with him in his office, why couldn't she just tell him what they were? Why did she have to keep them a secret from him? That's what caused his suspicion the most.

"Fitzgerald!" Mellie shouted, completely taken by surprise that he had said that. What was his problem today? "This is ridiculous. Absolutely ridiculous! Why can't you just believe that nothing was going on? Why can't you just believe that we weren't doing anything? I can talk to someone in their office without having sex with them!"

"Can you?" Fitz shot back.

Mellie took a deep breath, looking at him. "You're being disgusting." She stated simply, shaking her head.

"I'm being disgusting?" He was raising his voice, and he could tell that Mellie was getting uncomfortable by all of the staring and the looks that they were receiving from everyone in the hallway. But he didn't care. "No. I think I'm just trying to figure out why my wife was locked in a room with her boyfriend for half an hour! I have a right to wonder why you were in there. I have a right to believe that there was something wrong going on. Especially when you won't tell me the real reason you were in there!" He watched as she rubbed her stomach uncomfortably and without thinking, he spoke. "Is that child even mine? Or is that Andrew's baby? Are the twins mine or are they his too? Hell, are Teddy and Karen even mine? For all I know, you two could've been screwing around since after Jerry was born!" He stopped speaking when his brain caught up with his mouth, and he couldn't believe that he had just suggested that, that he had just accused her of that.

Mellie's mouth dropped as she looked up at her husband. She couldn't believe that he had just said that to her. She couldn't believe that he could doubt her so much that he would think that their children weren't his. She wasn't that bad of a person and he knew that. The tears welled up in her eyes and she threw a piece of paper at him, one that he hadn't even noticed was in her hand. She ran away sobbing before he had a chance to pick it up. He was about to run after her, but decided to pick up the paper first. As he picked it up and read the front of it, he immediately felt like an ass. He had felt like one already, but this made it even worse. It was an invitation to a birthday gala for him. That's why she was in Andrew's office. They were planning a surprise birthday gala. He had never felt like such an asshole in his entire life, and he knew that this was going to take a lot to make it up to her. He let his jealousy get the best of him, and he now realized how absolutely terrible that really was.

Fitz ran down the hall and after Mellie, hoping that she would let him apologize to her. But he knew it was no use.
