I can't

I could not imagine what it feels like to be you,
To spend my nights crying over someone else...
I cannot imagine waking up in her bed,
Screaming somebody else's name.
I cannot see her through eyes such as hers,
When you're yelling, and screaming, and crying for me.
It surely must hurt her to poke these holes in her fantasy.
I cannot imagine the nights through your mind,
The memories haunting your dreams,
But I am the only one well equipped
To handle your PTSD.
I cannot imagine to allow you to tear
My soul into pieces, my heart to despair...
I could not imagine the feeling you feel,
To cry over something that was never real...
I cannot put myself in your shoes...
The only one I cried for, was you.
