I have seen this posting on here for two days now, and no one has responded.... so I feel I have to...
THERE IS NO CURE FOR THIS VIRUS.
THIS VIRUS ALSO DOES NOT RESIDE IN THE LIVER. It lives else where, in or near the spine.
Do more research.
As for your friend who has done the cleansings and not seen an out break in a while, some people never have out breaks. Others suffer from severe out breaks all the time. It depends on the person, but does not mean that they are not still carring it and could pass it on to someone else.
If this girl has the virus, and you wish to evolve your relationship into something of a physical nature then the best you can do is religous use of condoms and avoidance of contact with sores.
This virus is highly communicable, but that doesn't mean that you can't still have a productive relationship with her.
Best of luck, please continue to research this more, and refrain from listening to those who would have you believe something that is not backed by proveble facts and statistics.
there are groups for those who suffer from this virus as well as groups for their partners. They can help you more.
