How could you

Nicole's pov:

I was currently arguing with my boyfriend bill about him being quite rude to me over the past few days and I guess he had enough and shut me up with a slap to the face and a hard one too..tears filled my eyes and I slowly walked to the bedroom and packed a small bag. Bill ran after me and tried to get me to stop. I whipped around forcing his hand away from me.
"You don't get to touch me.." I demanded with hurt lacing my words. He was shaking slightly and about to break down but I didn't care. I was about to walk out of the house when I glanced over my shoulder.
"We're over...maybe we can talk when your attitude changes Bill Kaulitz." I slammed the door behind me and went to my best friend Gustav's house. I knocked on the door and he answered and saw me crying hysterically. He let me in immediately and I felt myself almost collapse onto the floor but his arms wrapped around me and placed me on the couch. I couldn't answer his questions it was like I shut down. My hands covered my face and he softly removed them. When he saw my cheek he gasped. A big red mark was left on my face. He hugged me and took my shoulders softly.
"Nikki..you need to be honest and answer me. Did bill do this..did he slap you..?" He asked nervously. I couldn't say anything but nod my head. He clasped his mouth and looked like he was about to cry himself. He embraced me again and I soon felt so tired I fell asleep.

Bill's pov:

When my hand made contact with Nicole's cheek my heart broke. I didn't mean to hit her..i was a dick to her in the first place and now I'm even worse by slapping her. I slid down the door and sobbed. What kind of boyfriend would do that..? Nicole's phone buzzed and my heart dropped. She was somewhere in Germany without a phone. I looked at her Lock Screen and it was a picture of me and her. I had her lipstick mark on my cheek and I raised a hand to my cheek and cried harder. We were so happy and I just had to mess it up. I had accidentally opened her messages and it was between her and Gustav.

Nicole: I love him so much it hurts..
Gustav: you really fell for bill didn't you lol
Nicole: yeah I did..he's so sweet and gentle and I love him so much

Those texts were from a few days ago before my attitude changed. I was just so overwhelmed I couldn't handle it so I took it out on the only person I cared about..I called Gustav to make sure Nicole was safe. He answered.
"Is Nicole with you..? She left her phone and I wanted to make sure she was safe-" my sentence was cut off by Gustav yelling at me in a whispered tone.
"Don't you dare say you wanted to make sure she was safe. The only reason we're in this mess is because of YOU. The poor girl has a bruise on her face because of YOU. YOU put her in danger..so don't say you wanted to make sure she was safe." His words brought me to tears. I knew he was right...
"We'll talk about this at practice." He grumbled before hanging up. I sat on the bed and cried myself to sleep. When I woke up my eyes were swollen and my face was puffy. I didn't bother with makeup and just put on a striped sweatshirt and jeans. When I pulled up to the studio the guys looked at me with disappointment which resulted in an awkward aura. I couldn't think about music and just wanted Nicole back. But did I really deserve her..? I mean I treated her horribly. 
"Are you fucking stupid?" Tom growled.
"I mean hitting your girlfriend..come on!" I kept silent. It took a few comments from the guys before I broke down.
"I know I fucked up! I know..and the worst thing is I don't know how to apologize! I don't deserve her or her forgiveness." I sobbed. It was silent before Gustav handed me his keys.
"She's at my house. Go apologize and don't even THINK about touching her until she lets you." He made the last part clear and I wiped my tears and nodded. I drove to his house and knocked. Anxiety seeped into my bones but I couldn't back out now. Nicole cracked the door open and saw me and was about to close the door before I stuck my foot in to stop the door from closing. I forced  myself in.
"I know you don't want to see me..but I want to talk.." she turned her back towards me and I sighed. I really messed up..
"What I did yesterday was so unforgivable and so was my behavior towards you for the past few days..I was not the boyfriend you deserve. Now if you don't want to see my face I get that and I'll never show my face to you again...just please listen.." I pleaded. Nicole turned around hesitantly that was when saw the bruise that were caused by my heavy rings. Tears started to fill my eyes. Out of instinct I reached to her face. Nicole pushed my hand back in a panic. I glanced at my hand and cried. She was so fucking scared and it was all my fault. I could tell she felt horrible so assured her it was fine. I went to leave but she begged me not to go. I looked at her in shock.
"Sure you were an awful boyfriend for the past few days but I don't want you to leave..I also do things I regret when I'm mad and I'm scared..but I don't want to see you leave I still love you.." she sobbed while trembling. I opened my arms and she ran into them. I held nicole tightly and she went limp and I took her to the couch where we held each other. She was still hesitant with my touch but I will do anything to prove I would be a better boyfriend..the boyfriend Nicole Deserves.
