Before and after

I think you're the best before
I accept you without any thingking
Your texts, your missed calls
It makes my happines comes
Then the hard parts come
She is come, You leave me
You throw me.. wihtout any sorry
And then you said you love her easily
You know? It's SICK
And then you're gone
To your new life
A few weeks, you say you love her
A different girl. Again
You know? It's SICK
I know i'm not perfect
But it doesn't mean you've to throw me
What is my fault?
I hurt you once
You hurt me twice
Is that all you wants?
To hurt me?
