It could have been better for us

I once was happy
But now I am not
I use to love you
But now live in pain.

Your actions were simple
But they hurt so much
I tried to forget it
And then to forgive you

But you did it again
And hurt me some more
But I loved you greatly
And and accepted your flaw

I didn't expect it
How could I have known
You left me in confusion
Have I done something wrong?

My forgiveness it seemed
To have no end
But I draw the line here
Already to far

My heart is broken
My senses are numb
I show no emotion
For there is none to be shown

It surprises me not
That you so easily forgot
I was there when you needed me most
But now you treat me like a ghost

I'll never forget you
I'm sure of that now
For what you did to me
Made me throw in the towel!

I give up now
Before I die
It could have been better
If only you tried!
