Elusive Exclusivity

It still lingers. I thought it would be over after I slept but it is still here. I wonder how I could still be so thoughtful about it even after all of the things that have happened and things that I have done. But why can't I let go? And why does it still hurt?
I just want to say it but then what is the point? It is already over and all I would be is venting my own fustrations at someone who is not the cause.
