Different but the Same

We are one, but I feel two,
Your heart is red when mine is blue,
When my eyes turn grey yours turn true,
How are we so different but feel just the same,
Feel so distant and so hollow,
But don't feel any shame,
I'm corruptive but you are the corrupter,
You've changed but so have I,
I miss what I thought was you,
But I kiss it goodbye,
It was a dream nothing more,
But I hate to see you leave my door,
You are moving on, so should I,
So at last I say goodbye,
To the biggest part of me,
We are the same,
So you'll never realy leave.
