It's All About Whom? Poem by Glen Martin Fitch

We cracked the code!
Not every problem's solved,  
but now at least
this much we understand. 
I wake up feeling blue.
I hadn't planned it-  
no one's fault. 
In this you're not involved. 
The things I'm grateful for
should give me joy. 
Your hug would help. 
No hug? So I feel worse. 
I frown and sigh. 
Your words become more terse.
If I am hurting
why would that annoy you?
Now I see
you start to wonder
(while with someone
constant, clever, cute, and kind,
who loves me for my faults
and lives resigned to forfeit
all you prize
to make me smile)
how in your presence
I dare NOT be glad,
as if in spite
I've chosen to act sad?
