I don't know why i keep loving you

I know the sun will rise tomorrow morning
When morning comes I know it brings the dew
I know a storm can come without a warning but I don't know why I keep loving you
I know that you can't help these things you're doing
Oh you don't mean to hurt me yet you do
I know if this keeps on you'll be my ruin but I don't know why I keep loving you
I keep waiting for the change that never seems to come
The change that will make you love me too
But I know from your past there'll be no changing I don't know why I keep loving you
I don't know why I keep loving you
