I, me, you (?)

I wondered how you felt,
I knew you met her bed.
I did some quiet talking
with the voices in my head.

Pretended to be like steel,
treason on your face was read.
It seemed you'd forgotten about us
when my heart was in my hand.

 Please remember what is real,
I know your sanity was misled;
Still, I won't ask you twice
with a promising road ahead.

Just tell me what it is.
Please tell me what is wrong;
If you cannot do this,
I'll sing you a sad song.

A song full of hatred
and sorrowful lines.
I swear to you I'll make it...
But I can't promise I'll be fine.
