Hello, I'm back again, I know it's been awhile… Thank you for all the lovely reviews, I really appreciate them! Inspiration hasn't really struck in awhile. This OS is set after Jay and Erin break up in Season 4 but ignores the fact that Erin left for New York. Also a separate timeline from the first chapter of this fic.

Nonetheless, I hope you guys enjoy this chapter!

All of the broken hearts and the stupid mistakes
Have got us to where we are

The blaring of his phone alarm woke Jay from a fitful sleep. He reached over to and blearily found his phone to switch it off. He sits up, looking around an unknown surrounding. Realising it was Will and Nina's guest bedroom, and that he and Erin were… Whatever Erin and him were, and the headache of Abby coming back came rushing to him. He couldn't believe his luck, just while everything was going smoothly with Erin and they had moved in together, the other shoe just had to drop.

He chuckled humourlessly to himself, "Yeah, everything is just damn peachy." He couldn't believe the mistakes he had made by not telling Erin of his past, by not being honest, and really, by not following up on the whole divorce thing, the first time after he had signed those papers.

Getting dressed and walking to the kitchen, he spotted Will making coffee and asked for one.

"Where's Nina?" Jay queried.

"At work already, I have a later shift today," Will replied looking at his brother over the rim of the coffee mug. He couldn't help but stare at him, like as though he's clocking him.

Irritated, Jay put down his cup, "What man?"

Will shrugged, "Have you spoken to Erin yet?"

Jay's eyes grew dark at the mention of his mistake. "No."

"Abby?"

"It's all cleared up. I resigned those damn papers, and this time, I filed them to make sure the divorce sticks. I pray I never have to see her again."

"Okay, so I shouldn't be expecting another call from her then?" Will replied, half asking.

"No, why?" Jay asked suspiciously.

"No reason, but I think you should really talk to Abby properly," Will lifted up his phone to show Jay the three missed calls he's gotten.

"What? Give me that." Jay snatched the phone from his brother's hand. He had long since blocked Abby's number from his phone, and in doing so, has not registered if Abby had been trying to contact him.

Will continued, "Look, I think that, if you really wanted to solve your mistakes, you need to make it clear to her." Jay rolled his eyes and walked off to his room.

Jay fiddled with the cup of coffee in his hand, spinning the mug around in its saucer.

"Hey Jay, I'm so happy you called!" Abby slid into the seat opposite him. "I've been trying to get in contact with you. Look I know I messed up with not originally filing for divorce, but I'm hoping we can put that behind us. You know, maybe start over?" Abby placed a hand over his.

Jay withdrew back, staring at Abby, "Abby no. Just no. Look no, it wasn't right for you to not have put the papers through. But we are now officially divorced. This was a huge mistake okay? We never really should've gotten drunk and gotten married in the first place."

Abby looked up in shock, "You think I was a mistake? I thought what we had, was…"

Jay looked up empathetically at her. "Abby, Abby. Calm down. No, I don't regret our past, but I do think the actual wedding itself was a mistake. Come on, part of you must have to right? We were both drunk, not in the right mindset, nothing. So yeah, our wedding was a mistake, but what we had is always going to be special in its own right. But it's the past Abby. I've moved on, and so should you. I've broken hearts because I wasn't honest. So right now, I'm here to tell you. To move on. Because I'm sorry, but we won't work anymore. Because my heart doesn't belong to you. It belongs to someone else."

Abby reeled back as if something snapped in her. "It's the pretty cop isn't it? The one I saw when I came to you at the station?"

Jay smiled shyly, "Yeah. Well, if we are going to be honest right now. Not currently, but yeah. She's the one."

Abby smiled and nodded. "She must really be something Jay Halstead, for you to smile that way."

Jay lips turned into a wry smile. "Yeah. I'm sorry Abby, I never really wanted this drama."

"It's okay, it's my lost really. I should know when to pull back when it's clear I've lost." Abby soothed. "Also, it really is like you to be apologising for your feelings even though you have no control over them. You have a good heart. She's the luckiest girl in the world."

"Actually no, I'm the lucky one." Jay whispered. Throwing a couple bills onto the table, he stood up and gave Abby a last final hug. "Thank you for understanding. Also, please stop calling Will. I think his girlfriend is finding it a little strange that a girl keeps calling him."

Abby smirked. "Yeah, don't worry I'll stop. I'm heading home in a few days anyway. Bye Jay."

Jay entered District 21 with a new resolve, to get Erin back. But of course, a case had to get in the way and there really is no resting when that happens. He couldn't speak to Erin until 3 days later, when the suspect was caught and arrested. They were finishing up paperwork and nearly everyone had left for the night.

Jay walked towards Erin to touch her arm. "Look, I know I screwed up. I made a huge, huge mistake. But can we talk? I'm probably the last person you want to see and speak to, but really. Please?"

Erin pursed her lips thinking about it. Finally she just nodded and looked up. "Meet me at mine in 30mins?"

Jay smiled. "Yeah, yeah sure I'll bring Chinese."

When Jay rolled up to their place. "Wait can he say their? He left after all." Jay thought bitterly. It was his fault that he left after all.

He took a breath, knocked and waited.

Erin opened the door to reveal her partner/boyfriend/ex-boyfriend's face. She took a step back to let Jay into her apartment and took the Chinese takeout that he had brought over. Placing them onto plates, she gestured for him to sit at the kitchen island.

There was an awkward silence that fell between them. Jay unsure of how to start, closed and opened his mouth a few times like a fish.

Erin just sighed and placed the plate of food in front of him. "Just speak your mind Jay. No other choice than to rip the bandaid off." Erin was honestly sick and tired of everything. She thought that Jay was it for her. But with the things that transpired in the last few weeks, and all the cases they've had with no down time in between, Jay was starting to really grate on her nerves.

Jay took a deep breath in, "Yeah ok. Look I want to start off by saying I'm sorry. I'm so so so sorry with what had happened the last few weeks. I should've told you earlier, and it was a mistake. The whole damn thing was a mistake. I should've told you, I shouldn't have left. I shouldn't have shut you out like that, just when everything good in our lives was coming together. I swear, it's over now. I signed the papers. I was the one that filed them this time, so there can be no issues in the future. I spoke to her, I told her that whatever she was trying to chase isn't there anymore. That my heart belonged somewhere else, to someone else."

Erin's breath hitched at the last sentence. Despite everything that had happened, Jay had been her only love. The only one that she had ever felt that strong connection with. That kind of love doesn't just disappear in a few weeks. God she still loved him, and she's over the moon happy that those feelings haven't changed for him either. She didn't know how to respond though, so she simply replied with a strangled, "Okay."

Jay's chest was pounding loud and clear in his ears, blood draining from his face as he heard her reply. He doesn't blame her though. He shouldn't have acted the way he did. Was he expecting her to welcome him with open arms? He needs to get his act together, and his head on straight.

Standing from his stool, he collected his keys and jacket, he stopped by Erin to place a hand on her wrist, a sign of comfort. "I know I don't expect you to forgive me straight away. But dear god I hope you still feel the same was that I do about you. But I want you to believe me when I say this. The moment I walked out that door those few weeks ago, I broke my heart. The same time I broke yours."

Erin felt her heart shatter even more, the words caught in her throat. She managed a, "Wait Jay…" But he couldn't hear her, because her door had a closed with a resounding thud, leaving her alone.

Yeah we'll look back
We'll look back and laugh

"Hey babe, you okay?" Jay Halstead startled up, glancing at the direction of her voice. Erin soon-to-be Halstead wrapped her arms around her fiancé's shoulders, giving him a kiss on the top of his head.

Jay was looking at an article on his iPad. "Hey Er. Yeah, no. Just thinking."

"Of what?" Erin glanced down at the article. "Of the biggest fight we've ever had, really?"

Jay was holding an article of a wedding announcement. Abby McSweeney and Todd Burke are soon to be wed this Saturday at a beautiful church wedding.

"Well, if you really think about it, Abby technically made us stronger don't you think?" Jay replied.

Erin climbed her way over the couch to perch herself near Jay's shoulder. "Stronger? What does that mean exactly?"

"I mean all the mistakes I made. We mended our broken hearts together in the end, and we came out the other side even stronger than ever. What doesn't kill us right?" Jay nudged her knee.

"Yeah, but it damn near did." Erin stated.

Things got quiet as Jay perused his iPad again. Then turned and looked at her. "Thank you for coming after me Er. Thank you for letting me put that ring on your finger."

Erin just smiled, "I don't think I could forgive myself if I didn't come after you Jay I knew a long time ago that you were it."

Jay stood up to give Erin a kiss on the side of her forehead. "You know what else I remember? How we made up for lost time."

Erin smirked and gave a small chuckle, "You do, do you?"

Jay just shrugged, "Yeah, I do."

"Hmm, I think I might need a little reminder though," Erin lowered her head to stare at Jay through her eyelashes.

"Yeah, yeah. Okay." Jay simply leaned down to collect her in his arms and covered her lips with his, He then proceeded to remind her of that night.

Yes, and I'm done. I'm getting stuck on inspiration for this. It's why I kinda did a rewrite of Chapter 1, but followed the storyline of Chicago PD a lot more.

Please give me any prompts if you wanted in the review as well R&R! Will really appreciate it.
