Hi Bambina,
I haven't been diagnosed for as long as you have but the origin is still a mystery for me as well. I too don't have outbreaks, so its unclear when I was exposed. And I too have had the pleasure of having to tell someone that I brought this to the table. It's rough but you deal and you give them all the info you have and let them take it from there. It will for sure be a mess, but a lot of good things come from the worst messes. I tried to trace my steps backwards but it's pretty much impossible and as hard as it is at first, in time you'll see that it really doesn't matter. It's definitely possible to go thru the most stressful times of your life and not have an outbreak. I consider myself very lucky, I've read some of the horror stories and I'm thankful I haven't experienced it firsthand. Everyone involved needs to know, including the spouses.
