What you need more than what you want

I need ally to just fuck off out my life. He's hurt me so much, put me through so much shit and I don't want this anymore. I don't want us. I don't want him. I don't want a friendship, I want nothing from him. He is never ever going to change and I'm done always being just an option in his life. He's an arrogant arsehole now and I don't even want to spend any time at all with him. Even when I ignore his texts and try to get him out my life he comes back, texting me all the time, he wont leave me alone. And I'll admit it, part of me doesn't ever want him to leave me. But I need that and I know I do. I'd rather be totally alone than made to feel like I do right now.
