How did they diagnose you with hsv1 genitally? did you have a culture of active symptoms that said hsv1?
The choice whether to stay on suppressive therapy or not is yours. If you do decide to stay on it - consider switching to acyclovir to save money.

$375 a month is outrageously expensive!! Anyway, generally genital HSV-1 causes less severe and less frequent outbreaks than HSV-2. Most people with genital HSV-1 have relatively few outbreaks, and some do not have another one after their primary outbreak. Also, there is less viral shedding (when you can transmit the virus to others even when sores are not present). Even though it is possible to transmit genital HSV-1, it is a lot less probable than HSV-2. Most people acquire genital HSV-1 from oral sex when cold sores are present. I would discuss with your doctor what you would like to do about the Valtrex. I'm not quite sure about stopping the drug and viral resistance - in other words, if you stop the drug and decide to start it up again later down the road for whatever reason, it might not be as effective. However, I'm not an expert and I would discuss this with a professional.
Good luck,
