Scott Lang/ Ant-Man

Your sister Liz was visiting for the weekend so Scott took the girls out so you could catch up. When they came back at five o'clock, Lillian was practically bouncing off the walls and babbling excitedly which was not normal behaviour for her.

"Scott, did you let her have a coke?"

"Yeah. I don't see what the big deal is," he shrugged. You let out a sigh and plastered on a smile.

"Liz, can you please take the girls down to the vending machine and get me a bag of Skittles?" Liz knew that smile all too well and took the girls away.

"Scott, how could you do that?!" you hissed.

"What? Give Lillian a coke? She asked me for one and said you never let her have them."

"You don't get it do you? When I tell her that I won't let her have coke, it's not because I'm being a mean mom, it's because she can't handle the caffeine in it."

"You should've told me."

"I did Scott! I told you this when you first took her out!"

"I'm sorry, I forgot."

"You forgot?! This isn't like forgetting to pick up milk at the store! This is my daughter's life we're talking about here! Surely you must understand!"

"I do! I love Lillian as if she was my own!"

"You have a funny way of showing it then! Blatantly disregarding her health!"

"I said I was sorry!"

"Sorry's not good enough! You know what? Maybe I don't even want you around her anymore." Scott's eyes widened at this.

"What are you saying Y/N?"

"I'm saying that... I want to break up." Scott stood gaping at you, unable to believe the words coming out of your mouth. He then looked sad and turned to face the door.

"Fine," he muttered. Just before he left, you called out to him.

"Please... don't let this affect our girls' friendship," you begged.

"Don't worry Y/N. I'd never deliberately do anything to hurt them." With that, he was gone.

T'Challa/ Black Panther

Lately you had begun to think of the differences between you. Maybe you were just too different. The next time you saw him, you'd have to end it.

*

The next time he was in New York, T'Challa had taken you out to a fancy restaurant. He had the whole place cleared just so you could have it all to yourselves. As you dined, there was a heavy silence over the two of you. At the end of your meal, T'Challa took your hands.

"Y/N, there's something I want to discuss with you," he said sadly.

"What is it?"

"I'm afraid that I can't see you anymore." You closed your eyes and swallowed the lump that had formed in your throat.

"I know this is hard, but I must think of my people. You know how they feel about outsiders." You opened your eyes and placed a hand on his cheek.

"It's okay T'Challa. This has been coming for a while. In fact if you hadn't ended it, I would've." T'Challa nodded and stood up, extending his hand to help you up. You took it and he pulled you into his arms.

"I'm sorry Y/N. I still love you and I'll always treasure the time we spent together."

"I love you too. I understand. Your people come first. You're a good king." You both stood there holding each other for a long time. Even though this break up was mutual, it didn't make it hurt any less.

Steve Rogers/ Captain America

Steve had been on a long mission. The days had stretched into weeks, which turned into months. You talked to him once a day, then once a week, then once a month. This long distance thing really wasn't working.

*

The next time he called, you both talked until you ran out things to say. Just before Steve hung up, you stopped him.

"Steve... lately I've been thinking about our relationship and believe me this is not something I want to do over the phone but..."

"You want to break up," he finished.

"I... I still love you Steve, but I can't keep living like this," you sobbed.

"It's okay Y/N. I love you too and that's why... I have to let you go." His voice was thick with emotion.

"You deserve someone that can take care of you and be there for you all the time." You both said your final goodbyes, wishing each other well in life before hanging up the phone. All you could do now was cry until you were out of tears. Even after that, you continued to sob until exhaustion finally took over.
