She knew. The moment he walked through that elevator she knew. It was written all over his face. Guilt. Sadness, stupidity. All of it was practically written on his face in bold letters. It showed her everything she needed to know.

She couldn't even look in the eyes of the man who she once trusted. The man who promised to love her forever. The man who said he would never leave her. Yet here he was doing exactly what he promised he wouldn't.

She watched as he has proven his love. As he has begged for her love. As he has done anything and everything to prove to her that he wouldn't hurt her like everyone else. That she could trust him. But it was all a lie. One big lie.

She couldn't even get a word out to her fiance. In fact, he didn't even know she knew. Natasha was walking in the halls of his art museum, which he opened up due to Natasha's encouragement after retiring from the Avengers when she saw him locking lips with Sharon. Which was beyond disgusting if you think about it. If you he loved her aunt and things had turned out differently. Had he and Peggy had a relationship then she would be like his niece. It was sick.

"Hey, honey how was work." He asked her poring himself a glass of water. Natasha didn't respond she was too busy looking at the phone to register at the hotel.

When Steve realized he wasn't going to get a response from her he looked around the house. At the door, he noticed there were two bags at the door. He frowned because Natasha hadn't told him about any trip she would be going on.

"Are you going on a trip?" He asked her, annoyance in his voice because he hated when she left him.

"yes." She said and Steve could tell she was angry. He always knew Natasha mood changed. And he knew the moment she looked up into his eyes why she was angry. Her eyes were red and puffy, an indication she had been crying. His heart clenched.

"Natasha..." He said softly.

"Why?" She asked Steve was confused by her question.

"Why what?" He asked. There was silence for a moment, he just watched her as she stared down at her feet. She once again looked up.

"Why would you kiss her? Why would you do this to me?" She asked. Steve was at a lost for words. He didn't know what to say. What could he say?

"I don't know what you are talking about." He said, yes. He chose to lie instead of telling Natasha the truth. And he hated himself for it. He hated the fact that he chooses to hide it. But lying seemed like a better option than watching her heartbreak into a billion pieces. Little did she know, he already broke her.

"there are three rules in a relationship with Steve. Three simple rules. Don't lie. Don't make promises you can't keep. And don't cheat. And through our entire relationship, you have done all of those." She said. Steve looked down. "You wanna know how?" She asked with tears starting to fill her eyes.

Steve was hurting as well. He hated seeing Natasha upset. He hated it. Especially when it was all his fault. It burned at his heart like he was being burned alive. In fact, that would feel better than this. Anything would feel better than this.

"You lied just now when you refused to tell me, and lied right to my face claiming you didn't know what I was talking about. You promised to love me. But you didn't. You promised you would take care of my heart but you only ended up breaking it. And worst of all, you cheated. You kissed someone who wasn't me."

"No.. Natasha you don't understand!" Steve tried to explain. "it was a mistake!"

"No! Cheating is not a mistake Steve! Cheating is a choice." She said. Having had enough she stood and walked over to her bags. Steve looked at her and ran over to her practically falling on his knees hugging her waist. He couldn't, wouldn't lose her.

"Please don't leave me. Please don't do this to me." He pleaded not letting her go. But Natasha had tears in her eyes and was shaking her head.

"You did this to yourself." She said and pulled herself away from him. Steve couldn't move he was broken, in shock. Natasha was his life.

"Where will you?" He asked.

"Russia. two years. I have a mission." Two years. Two tears he would have to go without her. Two years of pain. How couldn't he move on?

"Please don't leave me, Natasha." He begged her. He couldn't go on. He had lost everyone he couldn't lose her too. He couldn't take that pain. It was too much.

"the truth is, I was already gone the moment you put your lips on hers." She said. Natasha put her hand on the door and it would be the last time she did so for two years. She left, the only sound was the sound of Steve's cries.

She left. She left because of him. She left because of what he did. He promised to love and care for her. But just like everyone else, he broke her. without even a look back she left him. She always hoped that he would be different. But of course, he was just like everyone else.

2 years later

Steve Rogers was a broken man. Ever since his fiance left him to go to Russia. His museum closed down due to lack of payment. He was almost thrown out of his apartment but luckily for him, Tony Stark helped him out. All the former Avengers tried to get Steve focused on anything else besides Natasha put it didn't seem to work. In fact, the only thing Steve did now call Natasha. He had only gotten in touch with her a year after she had left, and their conversation didn't go as planned.

"Yeah"

"Natasha, It's Steve."

"Steve. What do you want?"

"Please, can we just talk?"

"There is no need to talk Steve. It's over! You cheated on me."

"Natasha please let me explain it. I would never cheat on you! I love you! Sharon kissed me. I didn't want her to."

"I can't do this... not now."

"Tasha Please!"

She hung up on him. He was just surprised that she even picked up. But since then he has tried emailing, calling her, texting her, even writing stupid apology letters. But he never got a signal thing in return. Never once.

He missed everything about her. Her smile, her laugh, her voice, her hair, her eyes, her humor, her sarcasm, her cries, her everything. He needed her and craved her.

But today was a new day. He knew that she was coming home today. He would finally have a conversation with her. He would finally be happy. He can get rid of this guilt that has been clawing at his heart like a rabid beast. He just had to see her smile one more time.

So he put on his nicest shirt, the one Natasha bought him. Ever since she left and taken everything out of their apartment it has been so bare. It looked as if she had never taken a step into his apartment. And he hated that.

He walked over to the shield launch pad, where her plane would be landing. He was greeted by Tony and Pepper. Clint was also there but he refused to speak to Steve ever since the accident. Not even a simple hello.

"Are you excited capsicle? Little red is coming home today!" Tony said smirking at him, Tony was one of the few who believed him and was actually rutting for 'romanogers' to get back together.

"Yeah, he is excited to hurt her," Clint muttered.

"Clint, how many times do I have to apologize?" Steve said. "Please, it was a mistake."

"Just like Nat said, it was a choice. " Clint said. He turned away from Steve to look out for Natasha. Pepper sent him a helpless smile, to which he smiled a sad one back.

Out of the corner of his eyes, Steve saw Natasha walking out of the plane behind Maria and Fury. However, she wasn't moving like they were. It looked as if she was waiting for someone. Steve frowned when he saw walking with some guy. He had deep brown hair and had red sunglasses covering his eyes.

Natasha was smiling as he whispered something in her ear. Steve's heart was breaking. Was this what she felt at the sight of him? Was it this painful? He hated himself even more for letting it happen.

For the first time, Natasha noticed Steve. Her heart felt like breaking all over again. She didn't want to ever see him again. Those feelings that she spent two years putting away and getting over suddenly rose over her once again.

Then she turned away from him and saw her best friend. She smiled at him and the mysterious man beside her offered to hold her bag so she may say hello. She gratefully accepted as and walked over to Clint.

" Hey, loser!" He said with a smile on his face she smiled right back at her.

"Hey, idiot." She said embracing her friend. Natasha smiled in the hug as she reached him. It was nice. She really missed him and it had been way too long for the old friend.

"I missed you kid." He said to her as they pulled away from one another.

"I missed you so much more."She said. "And I can't believe I am saying this, but Stark I missed you too." She said smirking at Tony. She gave a hug to Pepper.

"It's good to see you Nat, and as much as he won't admit it Tony missed you so much." She said.

"No, I didn't. It was nice without her. Actually, when are you leaving again?" He asked. Natasha shook her head and smiled at her friends. Steve stood there awkwardly having been the only one who didn't receive a hello from the spy. He just stood there as the old friends caught up. How badly he wanted to wrap her in his arms and spin her around, instead he stood still watching the man who held her bags carefully sending him a warning glace. He must have taken a hint because he whispered a goodbye to Natasha before heading off with Maria and Fury.

"Um, Nat." He said but she seemed to ignore him, she was actually trying her best not to jump back into his arms. The others excused themselves saying they had business to attend to and Natasha took the chance to walk away. Steve had no intention of letting her get away. Not again.

"Nat! Please, I just want to talk to you please!" He begged. "Please." Natasha stopped dead in her tracks and turned to the super soldier.

"Why? Why on Earth should I let you talk? Why should I even give you the fucking time of the day!" She yelled her voice getting hostile.

"Because I am still in love with you! Because I want you to know that I can and will never move on from you! Because you need to know that my heart will only ever be full when I am with you." He said, his voice broken and hurt. Natasha felt her heart clench. She was still in love with him but he broke her.

"You hurt me, Steve." She said, her voice was almost as broken as his.

"I know. And that kills me every day. To know that you are in pain because of me! That you are breaking inside because of me! I deserve death. I deserve more than death, And believed me I have tried." Her heart literally broke at that. "I have tried to make it up to you by hurting myself but I can't seem to die because you are still alive. You are still alive and suffering."

"Steve.."

"I know I don't deserve you, Nat, I never can. Not after the sins I have done, the pain that has broken you to a point where you can barely stand in a room with me without tears coming to your beautiful eyes. I'm sorry can never take away the pain nor will it heal your broken heart, it won't make up for the mistakes I have made and it doesn't mean things will ever be the same ever again. But I am sorry is the start. The beginning of me realizing what I did hurt you It's me taking note that my actions broke you. I am sorry will never be enough to help bend your heart but I hope it's enough for you to realize that I never wanted to hurt you. I only can hope that you have it in your heart to forgive me." He looked down. "And if you never do it's fine. I will walk away with my head held low and will finally realize that I am not worth your forgiveness." He looked down and Natasha finally saw the broken man. The steve rogers who loved her, the Steve Rogers that never meant any harm. at that moment she knew. She knew he never wanted to hurt her. She knew the pain she caused him from leaving. She felt a sense of regret.

Natasha watched as his tear fell down his cheeks and he turned to leave. She watched as her own heart broke more than it possibly could. She had tears in her eyes. It only then did she realize just how much she missed this man. She missed him so much that she hasn't gotten a good sleep in ages. Those nightmares haunted her, that she hasn't smiled so happily since she left him. She knew he was her happiness and she needed him. He needed her. It was fate and who was she to deny fate?

Steve walked down the hallway. His steps were heavy and so was his heart. It felt like he had lost every ounce of will in his body. That he completely lost his heart. He was becoming a living corpse. But the moment he heard footsteps running down the hallway he became five times more lively. He turned and before he could fully turn Natasha jumped into his arms wrapping her legs around and connecting their lips.

Steve was shocked. For a moment he thought he was dreaming. For a moment he thought he was in heaven. But quickly realized he was on Earth with Natasha. His Natasha. He kissed back with such passion and love. He pulled away after a moment staring into her beautiful eyes.

"I am so sorry. I never meant to hurt you."

"I know. I know Steve. I love you. I always have. I am sorry I left. I was scared that I was going to lose you, and it hurt me so much!" She said and looked down at the floor. Steve used his finger to lift her chin.

"I will never leave you. I love you so much, please don't forget that. Okay?" He asked.

"okay. I love you Steve."

"I love you. I always will." And they kissed. Nothing would be the same but at least they were back in each other arms. Were the world wanted them to be. Were they were truly alive. And for once in two years. They were alive.
