What happened???

I've thought and thought...
I don't know what went wrong
I think it was you
But it could have been me

Girl I gave you my trust
But you didn't give a ____
I gave you my heart
But you just tore it to pieces

I don't understand you
I don't think I ever will
You lied to me
And you deceived me

Where were you
When I needed a hug?
Where were you
When I needed to talk?

Do you even know
What friends mean?
Do you know
What they're supposed to do?

If you don't know
Then look it up
If you do know
Then you know what you weren't

You put so much hate in me!
Sometimes you got on my last nerve
You were such a _____ at times
I just can't believe you

As I looked back
Together in pictures
I can't believe we
Were friends this long

All your lies
I knew them
I'm not as stupid and crazy
As you _______ were
