Why can't I be single?

So I have completely separated myself from my significant other, but the only thing I have not done is change my FB status. Why is this part so hard for me to do? We havent talked or seen each other at all since around New Years. The last time I heard from him, he sent me the message I shared in my previous blog, and I responded by telling him I dont think we are compatible anymore and he should move on. Since then I havent heard anything from him, he hasnt changed his FB status to single, and I havent changed mine. I know this is such a teenage drama cheesy thing. I feel like it is final in every aspect except that one. I dont plan on going back to him, dont even want to, but to change that status, I dont know why I want him to do it first. I feel in a way I am giving him false hope because I leave it like it is, and I guess he thinks I am going to come back. But it has never changed when I have gone back and I know it wont now. And after being free from him for over a month, why would I go back? I kicked myself in the ass every time I did, and this time I definitely wont. So why why can I not conquer that last 5% of my goal, and change my status to single???
