Breaking me down

These tears are swelling up inside
And inside they will forever stay
Because i will not again cry for you
And I'm sure you think this is o.k.

I've shed so many tears for you
Bitter with my pain
You can't keep doing this to me
My eyes are always in the rain

Why do you do this?
Why don't you know what's wrong?
I'd thought you would figure it out
Since we've been friends for so long

It hurts that you hurt me
But you know what hurts even more?
To know that you have no clue,
That you've broken my heart right down to the core.
