I saw this prompt in a Facebook group called SwanQueen Fanfiction, and shortly after was messaged and asked if I could take a stab at writing it, I did, and this is the product of that! I hope you'll enjoy it, and there are more chapters to come :)

It had been an exhausting, overwhelming, and all-out infuriating day.

For starters, her alarm didn't go off, so she had been late to the town hall meeting.
Then she dropped her phone in the sink while washing her hands in the bathroom... ruining it.
A few hours later Snow had a ludicrous idea to build a five-hundred thousand dollar daycare center right down the street from the elementary school, but when Regina had stated that she didn't think that'd be a good investment idea for the town, the board members disagreed and outvoted her.
Then, finally, the worst of it all happened: she'd gotten into an argument with Henry via text message because he had informed her he once again wouldn't be returning home this week…. The fifth cancellation within three months and the Mayor just wanted to see her baby boy.

She had been having quite a few days like this in the past few months, and she had no clue as to why they were happening, but she was indubitably fed up with it all.

So, yes, Regina was in a horrid mood… In fact, she was more infuriated than she had ever been in her life in Storybrooke; and coming home to her overly loving fiancée was the opposite of what she needed.

What she needed, was a Valium and sleep, what she was offered, however, was a welcome home kiss, an already prepared meal, and Emma blabbering on and on about how happy she was that they were finally alone together because her day had been exhausting.

Within moments, Regina had already had enough, and she slammed her hand down on the kitchen counter, startling Emma. "Would you just shut the hell up for ten minutes?!" She yelled.

Emma's smile fell automatically, and Regina couldn't find it in herself to care. She wanted to, but she didn't. "I-… I asked you if you were okay, and you said you were fine. I asked you if you wanted to hear about what happened at the Station, you said sure… If either of those were false statements, you could have just been honest, and we wouldn't be talking about it right now." Emma said, her tone lined with hurt.

Regina shook her head. "I don't give a damn about your day. I'm tired, my feet hurt, and I'm hungry."

The corners of Emma's lips slightly curved downwards. "Well, you can sit down and eat, and afterward we can sit on the couch, and I'll massage your feet while we watch TV." She said, her tone cautious; as if she wasn't sure that's what Regina wanted and was terrified that she'd said the wrong thing.

"Right, because I want you to manhandle my feet while I watch your petulant shows." Regina scoffed, she couldn't help it, she'd been bottling up her anger all day, and it felt good to finally let it out.

"I… okay, well I can start you a bath? I'm sure the hot water would feel nice on your feet, right?" Emma was trying her hardest to hold back her tears. This wasn't like Regina, she was usually happy to see Emma, but lately, Regina had been coming home angry. Emma had no idea what she'd been doing to cause her fiancée to be so mad at her all the time, she'd tried and tried to get Regina to open up about what was going on, but it seemed as though Regina was wholly intent on shutting her out as of late. All Emma wanted was for Regina to be happy, and whatever it took to make her smile again, she would do without question… If she would just tell her what that was.

Regina could tell what Emma was doing and knowing that Emma felt that Regina's anger was her fault, that the Sheriff felt like she had to fix whatever was going on, only further angered Regina… Made the cause of her anger switch from the events of the day, to herself because she knew that she had made Emma self-conscious; and it only made things worse. "I want you to leave me the hell alone and let me eat in peace! The last thing I need right now is you badgering me. You do realize that your constant attempts to find ways to please me have the opposite effect, don't you? All you do is get on my nerves when you're like this."

Emma had tears in her eyes. "Well maybe if you would just TELL ME what you want instead of blowing up at me and saying that you're 'okay' all the time when you're clearly NOT I wouldn't have to act like this! You never open up to me anymore, you never tell me about your day, you never tell me how you feel no matter how many times I beg you just to give me even a little crumb of a detail about your day, about how you're doing, about what you want!
I feel like I'm always walking on eggshells around you! I ask you if you want to go to Seattle to visit Henry and the next thing I know I'm getting bitched at because I'm being 'annoying' or 'clingy'! It's like you don't even want me around anymore!"

Regina scoffed at the mere thought. She couldn't live without Emma, and anyone who thought otherwise was an utter fool. "Oh, please! If I didn't want you around anymore, I'd have already asked for my ring back."

Emma clenched her jaw, her heart burning with grief and anger from the way Regina was acting. "Maybe you should!"

The vitriol in her tone, the seriousness of her voice, and the meaning behind those words, unsettled Regina in a way she hadn't felt in years. The fact that Emma seemed to believe that statement blinded Regina with uncontrollable rage that she hadn't felt since her days as the Evil Queen, and without thinking she cocked her arm and hauled her fist straight at Emma's face.

She pulled her arm back, prepared to throw it at Emma once more when the realization of what she'd just done hit her like a semi, and she dropped her arm to her side. Her heart shattered, her stomach fell to the floor, and her eyes widened in horror as she looked at the woman she loved and saw her busted lip.

A broken sob fell from her lips. "Emma." She choked out. "Oh, fuck… Emma, I-." She was cut off by the ring on she proposed with slipping off Emma's finger and being thrown at her feet.

"Save it," Emma said coldly. "I'm not doing this again. I did it with Neal, I did it with Hook, I did it in almost every foster family I lived with growing up, but I'm not doing this with you too. You were the one who made me realized that I deserved more than this. More than being yelled at constantly. Deserved more than being shut out, neglected, and hit. We were so happy three months ago Regina, but recently you've turned into someone I don't even recognize anymore, it's like I'm living with a stranger!
I was going to persevere through this with you, and I was willing to put up with the abuse because I love you, and this isn't like you at all. I was going to fight for you, for us, but this is crossing a line that is unforgivable." She paused as she pointed to her bloody lip. "You have turned into Hook two point o, and I'm not going back to that. I've tried to make you happy, tried to talk to you, tried to fix whatever happened to make you so angry, and you refused. We're done, Regina. This relationship has turned into a toxic one just like all the rest of mine. Maybe it's just my doom to be single, maybe I'm unloveable, but I still don't deserve this, and I'm not taking it anymore."

"No! Emma, please!" She begged. She didn't want to lose Emma, she'd finally found her true love, be it fated or not, and she did not want to let her go. She had survived losing Graham, survived losing Robin, hell she even survived losing Daniel, but losing Emma? She might as well go and pick out her tombstone. "I'm so sorry, I don't know what got into me, but I swear to god it will never happen again!"

Emma had tears spilling down her face as she looked at Regina Remorsefully. "That's what they all said too." She cried before she disappeared in a puff of white smoke.

Regina collapsed against the counter, her heart aching, her body racking with gut-churning sobs, and her eyes flooding with remorseful tears.

What the hell is wrong with me?
