Why did you?

Why do you always pretend?
That you will be the one who will mend
This broken heart of mine
If what you only knew are lies.

You said you love me
But why did you do this?
You just ruin my life
Stabbed me with a knife

You are the one who broke my heart
The one who let me fell apart
Is this what you will pay back
To all the love you got?

Please let me know
So that I'll let you go
And I can move on
To find the right one soon.
