Saviour from synthetic love

Why are you laughing?

'Im just not happy any more, ok?' I said for what felt like the hundredth time.
'You mean it?' Sam said, a concerned look on his face.
'Yes' I practically shouted at him. He started laughing... wait, laughing? 'What? Why?' I mumble to him,
'you have no idea how stupid you sound!' he giggled to me. A vicious smile spread across his face, what was he playing at? He suddenly grabbed me by the neck and threw me to the floor. 'Wha-' I tried to shout out but he covered my mouth.
'Shhh, don't answer back bitch!' He slapped me as hard as he could, then leaned close to my right ear.
'Once together, always together. Got that?' I nodded, tears rolled down my cheeks.
-later that evening-
'What am I supposed to do!' I sobbed to my best friend, Hannah.
'Your dad did treat you a lot worse, so you can handle it emotionally. I guess' she said. I felt a bit better because she is not good in those situations. All the relationships she has been in, ended on happy terms. Plus she is engaged to a guy called Luke Hemmings, Hannah said he treats her really well and that's very nice to know.
'I guess, maybe I should just make some sort of system to avoid him' I remarked, calming down.
'Good idea, I will help!'
