paramore, The only exception lyrics?

So in the song Paramore sings "The only exception" it goes like this:

And that was the day that I promised
I'd never sing of love
If it does not exist

But darling,
You, are, the only exception



What exactly is this song about that she is singing about love where it does not exist or am I misunderstanding what she is trying to say. She said she promised she would not sing of love if it didn't exist, but apparently this song is the exception.
