A re-write of : "I'm through with that boy"

Why don't you understand
That we really can't be together
I should have known
That this couldn't last forever

Now my heart is broken
My mind is quickly racing
Tears are falling from my face
Leaving my pulse is pacing

He broke my heart
And he made me cry
Now there's no more love
I just had to say goodbye

Sometimes it seems
That I did the right thing
Why didn't someone tell me
He only saw it as a summer fling

Now my heart has no more happiness
It's no longer filled with joy
We are finally over
And I am through with that boy

He made me cry
Way too many times
But time will move on
As the old clock chimes

Time is slowly moving
Minutes slipping away
But there are no more words
For what I have to say

Because I loved him so much
But he broke my heart
In front of my eyes
I saw my world fall apart
