Why?

I thought you were my best-friend
That I can trust you with every minute that I spend
I thought you were the best
But that all bring me into mess

You lied to me at the time I must trust you
You tricked me when I was feeling blue
I never thought you'd hide me things I must know
Never imagined our friendship would be gone in a blow

I want to kick you out
And to you I shout
But I can't do these now
Cause I don't now how

I told you secrets I hid to others
That thing didn't make me bother
For I believed you're true
And I gave our friendship too much value

I am not emotional but today I am
Don't know how to react to this problem that came
I want to cry, I want to slap your face
Just to let this feeling be vanished at once

Now, I'm still longing for you to explain
Tell me why you gave me this pain
I'm asking you now so please reply
And give me the answers in my questions "why?"
