Single?

I'm single now. It's uncomfortable. I'm so used to having someone worrying about me, him being angry at me because he misses me, texting me or messaging me on Facebook silly memes, being annoyed when he's high or drunk, telling me about his day at work, telling him about my day at work, him groping and embarrassing me in the grocery store, hearing him moan and groan about how bad his back hurts, him spitting chew out my car window and being grossed out about it, how he smelled, yelling at him for leaving his slippers in the middle of the floor...now I refuse to move them from the exact spot where he left them. All these stupid little thing felt so insignificant at the time. Now I oddly miss it. I feel like I am floating in limbo. If someone asked me if I was in a relationship I think my response would still be yes. Like he's right here. But he's not. He will never be again. I also feel a sense of freedom. I can go certain places, do certain things and even eat certain food and no one is there to question me about it. What is this feeling? This is new.
