The lesson to forget

I've been deceived!
What have you done?!
I really believed,
and now it' s gone!

You broke it all!
What did you win?!
You slammed the door
and left "the scene"!

I didn't see it comming!
How could I expect?!
"The end" of our story!
How could you forget?!

I should hate you to the grave!
But what I'll do instead
is to follow the lesson you gave-
you taught me to forget!
