Taylor Swift - "Tell me why"

Once again... giving advice didn't prevent me from commiting my own mistakes. I told you don't go there. But I went. To my most recent dark corner. 'Cause I just can't help it. And now I'm hurt, left wondering, analysing every word and just wishing "God! Let that not be what I think it is!"
Don't they say that if you wish something really hard, it will become true?
I just don't know what I did to deserve this. And I want it to stop! Or will I have to run away?
Will you accomplish that?

[Out of "Espelho meu... Reflexo nosso". Thank you Cária for posting this. It is the perfect aftermath of my last post and today's afternoon]

"I took a chance, I took a shot
and you might think i'm bulletproof, but I'm not
you took a swing, I took it hard
and down here from the ground I see who you are

I'm sick and tired of your attitude
I'm feeling like I don't know you
you tell me that you love me then you cut me down
and I need you like a heartbeat
but you know you got a mean streak
makes me run for cover when you're around
and here's to you and your temper
yes, I remember what you said last night
and I know that you see what you're doing to me
tell me why..

You could write a book on how to ruin someone's perfect day
well I get so confused and frustrated
forget what i'm trying to say, oh

I'm sick and tired of your reasons
I got no one to believe in
you tell me that you want me, then push me around
and I need you like a heartbeat
but you know you got a mean streak
makes me run for cover when you're around
here's to you and your temper
yes, I remember what you said last night
and I know that you see what you're doing to me
tell me why..

Why... do you have to make me feel small
so you can feel whole inside
Why... do you have to put down my dreams
so you're the only thing on my mind

I'm sick and tired of your attitude
I'm feeling like I don't know you
you tell me that you want me then cut me down
I'm sick and tired of your reasons
I've got no one to believe in
you ask me for my love then you push me around
here's to you and your temper
yes, I remember what you said last night
and I know that you see what you're doing to me
tell me why
why, tell me why

I take a step back, let you go
I told you I'm not bulletproof
now you know..."

Don't be literal about this. I'm sure you'll know how to read what you need to into it. I'm not the complicated one here...
