(this chapter is going to be focused on just Emily and Aaron's past because it's the last one of the flashbacks, hope you enjoy :)

20 years earlier-

Emily and Aaron had been together openly ever since Elizabeth said she wasn't going to let their relationship affect his career. They were never apart most weeks, staying alternatively at either of their houses. Aaron had started going to quantico every week for 3 days, which always had Emily on edge that he was going to be accepted early and he'd leave. She liked her personal space in the time Aaron was away, but she obviously missed him a lot during the days he was gone.

Valentines Day was coming up but Emily wasn't expecting anything as it was fell on the days Aaron was supposed to be training and it had been extended this time. She was obviously disappointed, it was their first Valentine's Day together but she knew it wasn't a big deal. After all, it was only another day. It was only the fact all of her friends were spending time with their partners that would make her feel more alone.

"So..I'll see you in 4 days?" Emily said as Aaron put his stuff in the car.

He nodded, moving down and kissing her softly, "Yes, and then I'll make it up to you for missing valentines." He said, placing a hand on her face.

She shook her head, "I told you Aaron, it's okay..I'm not bothered. I'll spend valentines with a tub of ice cream, watching breakfast at Tiffany's" she said with a light chuckle.

He chuckled and pecked her lips once more, "Goodbye Em, I love you."

"I love you too" she said with a sigh before he got in the car and left.

Emily had spent the last couple days doing some retail therapy, she had the tendency to overspend. Before she knew it, it was Valentines Day. All day all she'd seen are couples giving way too much PDA and all over each other, although she could never dream of her and Aaron being like that, it did make her feel a little more alone.

Emily was in her pyjamas, she'd just got a tub of ice cream and was about to put on breakfast at Tiffany's, as she had said she would. Suddenly, she received a knock on her door, she was confused as to who it was and went to go open it.

Her eyes widened as she opened the door, "Aaron?" She said with a smile.

"I came back early, the case finished...and I brought you these." He said, revealing a bunch of roses from behind his back.

"Your amazing" she said with a laugh,pulling him closer to kiss him passionately. "And these..are beautiful, my favourites." She said as she placed them on the side.

"I didn't manage to book us anywhere..because I didn't think I'd be back-"

She shook her head, pulling him in for another kiss, "I'm not bothered..just you being here is all I want." She said, moving backwards onto her bed, not breaking the kiss.

"Someone's eager." He smirked, unbuttoning the buttons to her pj top.

"It's been too long..and by that I mean 3 days too long." She said in between kisses as she pulled the tie off his shirt off.

He grinned as he heard her, roughly pulling her pj shorts off along with her underwear as she unbuttoned his shirt, taking it off instantly.

He grabbed her throat roughly, inserting two fingers inside her, Emily moved her head back moaning softly.

As he started going faster she bit her lip, holding in a moan.

He made his way down, and sucked on her clit as he continued to move his fingers inside her, she moaned as he did moving her hands onto his shoulders gripping into him.

He looked up at her with a smirk, he could tell she was getting close, he knew exactly where her soft spot was.

He continued to suck her clit, moving his fingers fast inside her, she couldn't hold it in anymore as she felt herself release. "Fuck" she moaned, he smirked as he saw her release.

He moved his hands down to his pants, unbuckling his belt and taking his pants off along with his underwear as he made his way back up to kiss her. He was about to enter inside her when she grabbed his elbow, pushing him to the side of her and sitting on top of him.

He smirked as he made eye contact with her before she moved her head down to his dick, sucking on it at a slow pace to start with. As she starting sucking faster, she moved her tongue up and down his dick, as she started using her hand to toss him off at the same time.

A groan escaped his mouth as he moved his head back, closing his eyes as she continued.

She moved her head back up to look at him, as she did he grabbed hold of her waist, pushing her down onto her back and roughly entering into her.

A loud moan escaped her as he entered in, her hands gripping the bed sheets as he thrusted fast. He moved down and started kissing her neck roughly, trailing down and kissing every part of it. She pulled his face back up, kissing him passionately as he pulled her legs up onto his shoulders thrusting into her deeper.

She moaned as he slammed into her rougher, as he moved a hand onto her neck roughly.

"Aaron.." she cried out, biting her lip. He smirked as he pulled away from her, pushing her backwards onto her knees and roughly inserting himself back inside her.

She moved her head up, biting her lip as she arched her hips. He grabbed her waist, pushing himself roughly into her. He slammed into her deeper, as she gripped her bedsheets, letting out another moan. He pulled her hair from behind as he continued to thrust, he groaned in pleasure as he felt himself cum inside her.

"Your amazing.." he said, pulling out and pushing her forward to kiss her. She chuckled, "I think after that...your the amazing one." She said, placing her hands around his neck, deepening the kiss.

They both pulled away and sat up, "This was much better than some reservations somewhere." She said, kissing his cheek.

"Since we can't get any, do you wanna order in?" He asked.

She raised a brow, "You don't have to ask me twice..I'm thinking Chinese."

"What if I said no?" He smirked.

"I could think of ways to persuade you.." she said, trailing her hand down to his dick.

He looked down at her hands and back up at her, "I'm listening.." he grinned, as she made her way down.

An hour later they had both ate dinner, and were in bed watching breakfast at Tiffany's with ice cream, much to Aaron's disapproval with the movie choice.

"Emily...there's something I want to ask you." He asked, as he played with her hair.

"What is it?" She asked, looking up at him as he head was on his chest.

"Well..I've been thinking..and I was wondering, if you want to move in with me?" He asked, raising a brow.

She widened her eyes as a smile grew on her face, "Are you serious?" She asked, sitting up.

He nodded, "Yeah..I mean, it makes sense. You'd have more freedom instead of being in your room..and we could do whatever we like all around the apartment" he smirked.

She nodded repeatedly, "Yes, of course I will!" She said before wrapping her arms around him. "I love you" she whispered as she buried her neck into his neck.

"I love you too." He chuckled, kissing her cheek.

Since Emily and Aaron moved in together, Elizabeth had signed her off for any security anymore and Aaron had been relocated to somewhere else in security.

It was a late Sunday morning, and Emily awoke to the smell of food being cooked. She sat up and saw Aaron had already woke, she looked at the clock and saw it was 11:30. She chuckled to herself, she had warned Aaron she wasn't a morning person and Sunday's were even lazier.

She had slept in one of Aaron's shirts and got out of bed, making her way to the kitchen. She wrapped her hands around his waist from behind, kissing his cheek, "Good morning." She whispered into his ear.

He smirked, turning around to kiss her, "More like good afternoon almost." He chuckled, looking her up and down. "Why do my clothes suit you so much more?" He added.

She laughed a little, as she poured herself a cup of coffee. "What have you been making?" She asked as she sat on the kitchen counter.

"I've been making your favourites..pancakes. At first, it was a fail...but I think I've perfected them now." He said, showing her a plate of pancakes, versus the burnt ones in the corner.

She smiled, "A for effort, Aaron Hotchner." She said, kissing him softly.

She moved over to grab a fork and took a bite of a pancake, "So what do you think?" He asked, raising a brow.

"I think..these are amazing.." she said, closing her eyes in pleasure.

He smiled, getting a fork and taking a bite himself, "I'm glad you like them"

"I can think of ways I can thank the chef for these.." she smirked, wrapping her legs around his waist and pulling him closer.

Months had passed, and everything was perfect between Emily and Aaron. Moving in with Aaron was the best decision she had made and she hasn't been happier. They hadn't argued, except the few bickers and it had felt like the new honeymoon period of their relationship had never ended. However, their time together had been getting shorter, September was creeping upon them both and Emily was off to Yale soon. As much as she wanted to go to Yale, she wished she didn't have to leave him.

It was Emily's moving day, her boxes were all packed and sent in a moving truck and Emily and Aaron were headed to the airport. It was an almost silent trip, neither of them wanting to arrive at the airport.

Once they had checked in, Emily was waiting for her flight to arrive. As she heard her flight be called, Emily looked at Aaron and sighed. They both stood up from their table, and instantly took each other into their arms. "I don't want to go.." she said, her voice breaking as tears fell from her face.

He shook his head, "it's going to be okay..we will still see each other, and Yale..is an amazing college and it's where you've always wanted to go."

She nodded, pulling away and kissing him softly, "I love you."

"I love you too." He said, wiping the tears from her face. "I'll call you when I land." She said, putting her bag onto her shoulder.

He nodded and kissed her once more, "I look forward too it. And I'll see you in a month, remember?" He said, smiling a little even though he was sad she was leaving. He was going to miss her terribly.

She nodded, quickly hugging him once more, "Goodbye, Aaron." She said, her voice breaking as she walked off.

"Goodbye." He whispered as he watched her leave.

Throughout the months, it was hard for them both. Aaron had been accepted into the FBI's BAU and worked there full time which put more distance between them. Emily was studying almost every night, her workload was high and they barely spoke on the phone. Neither of them liked this, it had been almost 2 months since they had been together but Emily was going up to Aaron's apartment for the weekend in D.C. They had both spoke about this for weeks, both excited and prayed nothing was going to stand in the way. To make sure he had the time off, he had used a few days of his holidays.

As Emily walked into DC airport, she scanned the airport to try find Aaron, and as she laid eyes on him she ran into his arms. Hugging him tightly, not letting go. "I missed you so much." She chuckled, kissing him softly.

"I've missed you too" he said, moving a hand on her face. "I can't believe your here."

She shook her head, "Me neither."

"I plan on showing you everything.."

"I hope that starts in the bedroom, Aaron Hotchner." She whispered.

He smirked, as he grabbed her bag for her as they walked off.

Emily and Aaron were in bed together, her head was on his chest and he was stroking her hair. It was the day before she was set to leave, they had spent the weekend exploring D.C., Aaron had took her too all of his favourite places and they had long, passionate nights.

"I've missed this..and I've missed you. I wish I didn't have too go back so soon" She said sitting up.

He nodded, "you have no idea how much I've hated not being around you." He said, taking her hand and kissing it. "You have to go back..but, Christmas is soon." He said with a sigh

"I just wish it was different...this is only the first year of it." She sighed, putting a hand through her hair.

"I know..but at the end of it, it'll be worth it."

"Will it? Because I've been miserable, I just feel so lonely without you."

He nodded, "Me too."

As she was about to speak, there was a knock on the door, "Who's that?" Aaron asked, as he got up to go and answer it, quickly getting dressed.

Emily was intrigued, and put on one of Aaron's shirts as went to see who it was.

"Oh, she's still here?" A woman whispered.

Aaron nodded, "Yeah..she's here all weekend. You didn't have to bring coffee." He chuckled, as he sipped his drink.

"I wanted too" the woman smiled, putting a hand on his arm.

Emily watched from behind the wall, her eyes widening, was he seeing another woman? She certainly seemed friendly and she was acting suspicious about Emily being there.

Emily walked out, "Aaron?" She said, coming next to him.

"Oh, Em..this is Diana, we work together. Diana this is Emily" He said softly, with a small smile.

They certainly looked like more than work partners she thought.

"I'd love to stay..but I've got to go. I didn't realise..you were busy, Aaron." Diana said smugly, looking at Emily. She placed a hand on his arm and squeezed it, smiling at Aaron before starting to walk away.

Emily scoffed, this woman wasn't even hiding it, the least they could of done was wait till she wasn't with Aaron.

"Who was that?" Emily folded her arms, turning to him.

"What? I just said- it was Diana, my work partner...I'm sorry she came across rude, she's just a busy woman."

Emily scoffed, "No, she was rude to me. Not you. She was quite happy to be friendly with you when I wasn't there though." She spat out.

"Em..what are you suggesting?" He raised a brow.

"It's obvious, Aaron! Your seeing her! She was whispering asking if I was still here..and she brought you coffee! What work friend randomly pops round on a Sunday morning to give you coffee!" She said, raising her voice.

"Emily- it's not like that? You'd really think I'd do that to you?!" He said, getting angry at her accusations.

"Well, I don't know! Maybe you couldn't resist her..I mean, she's perfect for you. She's your age, she works with you,she's local. You wouldn't need to wait months to see her and she'd be local to fuck when you wanted!" She said, her voice breaking.

"I can't believe your even suggesting I would cheat on you!" He shouted.

She looked at him, "Maybe that's why you never seemed as keen on the phone..maybe she was round." She said as a tear fell, "I just told you in there I was lonely without you..and you lied to my face. Your not lonely, you have perfect Diana" she said storming into the bedroom, grabbing her things.

"What are you doing!?" He shouted, following her in. "I'm not with her!"

"How can I believe Aaron..you didn't see how she looked at me. She knew what she was doing and she enjoyed it." She said, throwing her things in a bag.

"She's a friend!"

"So your telling me she's never ONCE tried anything more?" She asked, "And you've never mentioned her before..I know all your other work friends."

"She's relatively new.."

"You didn't answer my question, has she tried anything with you?" She asked, folding her arms

He sighed, looking at her, "Yeah..she has. But I rejected her!"

"Then why didn't you tell me! And why have you continued seeing her if you know she likes you!" She shouted, her heart ached as she heard him admit that she had tried to kiss him.

"Because I didn't want you to think anything of it, like you are now! And she's a good friend."

"If my 'good friend' tried that on me and I had a boyfriend, I wouldn't continue seeing them!" She said, putting her clothes on.

"I can't believe you'd think I'd do that to you!" He shouted, "If you think that low of me then why are we together!?" He said in rage.

She gasped, "Do you not want to be?" She asked, swallowing.

"I- I don't know.." he said, softly. He knew he did, he loved her more than anything, but whatever he said he knew she'd made her mind up about the whole situation. He knew the distance was having a toll on her, she was distracted by him and he wanted her to not be held back by it.

Emily nodded, tears falling, "I get it now..the distance is too much. And you don't love me anymore. Just forget it Aaron" she said, her voice breaking, tears falling, as she walked out the bedroom and to the door to leave.

Hearing her say he doesn't love her anymore, almost broke him, of course he loved her.

"Emily.." he said, walking after her.

"Goodbye, Aaron. " She said, opening the door and walking out, shutting the door and walking off

His hand was on the door handle, he wanted more than anything to open it and pull her close to him. To tell her he loved her and he didn't mean anything. That he would never cheat on her, and he couldn't think ever of doing. But he knew this was best for her. His heart ached as he saw her leaving, he couldn't believe this was happening. He was only saving her the pain later on, he wanted her to focus on Yale and success and he knew she was distracted by him. He didn't want to hold her back, he couldn't.

He walked into his bedroom, and punched the wall, as his eyes filled with tears. He had lost the only thing that mattered to him.

As Emily got into the street, she sat on a bench, tears filled her eyes as she broke down. She buried her hands into her head, she'd lost the only person who made her happy. As much as she wanted to go back up there and sort it all out, maybe she didn't let him have his say on the whole Diana thing, maybe she'd overreacted. She knew she couldn't, she thought this was what he wanted, he wanted to end things and he didn't love her anymore.
