0.91 is just one 0.1 away from being negative. I have no concerns that you have HSV 1, BUT
I think since you are worried about this, you should talk with your partner about this, just as you have spoken with me. And if she is still concerned or you are, you can get a herpes western blot from the University of Washington, either through your own provider or through me.
I would bet a whole lot of money, you are not infected.
