Missing Piece Poem by You... don't... want me...

Now you are gone,
And I’m thinking about it
Thoughts of our encounters run through my mind
The missing piece of the puzzle, is what I’m trying to find
But there is nothing, not a clue
In the last conversation I had with you
So now I search further back
Looking for the point of attack
But I come up empty again
Nothing harsh was ever said
God how I wish the answer would appear
Seriously, I have no idea where to go from here.
