You won’t leave me

I’m going to have to turn my back on you, I tell X. I’m too busy, I’ve got things to do and you bring me down. What are you talking about? he says. This is it, I say, you’re going to have to leave, I have to get on with my life, I’m busy. See you later. I know you, he smirks, you won’t leave me. See you later, I say, walking away. Come back here, he shouts, running towards me.
