Who's side are you on?

When you're single... Is it healthy to have a side of the bed? Or is it a daily (or nightly rather) reminder of what you don't have?

I miss the snuggles and cuddles, and pillow talk, and waking up in the morning and seeing an adoring face looking back at you.

I hate sleeping alone. It's one of the few times I actually feel single.
I think I'm gonna start sleeping in the middle of my bed from now on.
