Zayn’s P.O.V.:
I return in my shared flat with Perrie. I slowly open the door, throw my keys on the table and pull off my shoes.
“Perrie?” I ask quietly.
“Hum? Zayn? I’m in the living room.” She answers. “Is your ex feels ok?”
“Um… Luz. Yeah... She accepted us to help her, that’s a good point.” I say.
“Oh. Cool. So you’ll see her, like, much time?”
“Yeah. With the lads.”
“Ok. Cool.”
“You’re alright?”
“Sure.”
“Perrie?”
“What? You decided to get closer to your ex for help her… Cool.”
“You’re not alright.”
“Zayn… You… Uh… You stayed there until 9pm.”
“We were all there with her.”
“But… You…”
“If that reassures you, she doesn’t even speak to me.”
“That better stay like this. You’re mine.”
“Perrie… Seriously…” I tell her rolling my eyes.
I go to the bathroom and run me a bath. I slip slightly in the hot water and rest my head against the rim of the tub, and I close my eyes. I’m so sorry Luz. My little Angel. There is no step back, as you said.

*Flashback*
I enter in our living room. Luz is sitting on the couch, looking at me. Something is bothering her, I know her by heart, and she’s frowning. That’s typical Luz. She frowns when something bothers her.
“Zayn… We need to talk.” She tells me quietly. That’s a bad sign. We’ll have a fight.
“Hum? About what?” I ask her. Where’s the problem?
“That’s the fifth time… Um… You go out with Perrie…”
“Yeah, what?”
“That’s cool if you want to be friend with her but… do you need to be seen together that much?”
“Luz. She’s been my girlfriend for a moment before I met you. I have the habit of her.” I try to reassure her.
“Yeah… I know… but I feel like… like you replaced her with me… Like you needed to fill the void she left in you…” She whispers
“Come on…” I turn back, heading to the kitchen.
“But Zayn… I…”
“Ok. Stop. That’s Perrie ok? She’s important to me! She… She knows me more than you’ll ever…” Oh shit. What was I about to say here? That’s a complete lie.
“She knows you more than I’ll ever know you? That’s what you wanted to tell me?! I’ll never be at her level… That’s it?” She yells at me.
“Yes! She’s more than you’ll ever be! I love her! She still what I need. Happy?!” I squall on her, upset. Why is she so jealous? I’m not hers. I love her but can’t she just be normal and trust me? She’s so clingy sometimes.
“Ok.” She mumbles. “Ok. I understand. I… ok.”
I open the door and go out. I stay out for a moment, to calm down. I should not have shouted on her like that. I go back in the car and drive to our flat. I left since two hours. I open the door slowly. “Luz? Babe I’m so sorry…” I say out loud, searching for her. She doesn’t answer. I enter in our bedroom. She’s there.
“Luz? Do you hear me?” I ask her. She slowly turns to me.
“I’m going to leave.” She states.
“What? Wait… Why?”
“Zayn… She’s more than I’ll ever be. I just can’t stay there, waiting for you to come back home and imagine you with her. I’m going to leave. Fix things with her. If you love her and she loves you, then it’s ok. As long as you’re happy.” She says.
“But…”
“There is no step back. I’ll follow my own path and you’ll follow yours.”
“You can’t just leave like that.”
“Oh. I can. I called a cab. He’ll be there soon.”
“No. You can’t… leave me like that.”
“Zayn. I was there to fix you after Perrie left; now she’s back. You don’t need me anymore.”
“Luz… That’s not true.”
“Look me in the eyes and tell me that you love me, that you don’t love her. Tell me that you didn’t need me to fill a void but because you wanted me, that you needed me as just… Me. If you do that, I’ll stay.”
“I…” I can’t tell her that. I needed her to fill a void, but now, I love her. I love her, but Perrie too, because it’s hard to just stop loving someone like that. I can’t just forget her like that. I need time, just a little more time. “I need time.”
“That’s why I’m leaving you. Because I can’t stay here. I can’t share Zayn. I just can’t.”
Someone honks outside. Her cab. She grabs her suitcase and walks toward the door of the room. “I’ll come to take my stuff. See you, Zayn.” She goes out and enters in the cab. I go to the kitchen. I open the fridge. After five minutes of looking into it without taking anything, I return to our… my bedroom and lie on the bed. So she left me. We broke up. These eleven months with her were amazing. I’m gonna miss her. I don’t feel like it’s true. I feel like in an awful nightmare.

*End of the flashback*

I open my eyes and notice that I’m crying. After one year, remembering of that moment always makes me cry. God. Why didn’t I tell her how much I love her? I should have told her. She’ll always mean the world to me. Whatever. I’m with Perrie now. I have to convince myself that she’ll be my wife someday. I don’t move from the tub. I stay there, reminding of my life with Luz.
