"Simply Couldn't Care" lyrics

Why do these things bother me so
Why do I lie awake so long after you go
Arguments just prove we're not the same
We'll end up talking to ourselves
And it seems a shame

Well, I'm losing count
But I guess that you're still winning
How can you be so rational
When my head is spinning

Why did I let you get to me
Why couldn't I have stayed the girl I used to be
And you must hate the way I don't see things like you do
So get angry, prove your point, I'll believe you
You're maddening but you keep me awake
And I would scream at you but there's too much at stake

Why is it when you were there
I'll fight about anything else
I simply couldn't care
