tell me why

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 reasonsI got no one to believe in
You tell me that you want me, then push me around
