Tell me why

I took a chance, I took a shot
And you might think I'm bullet proof 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 and 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?
