GuitarGuy.....sorry to hear your marriage may be on the rocks. I am not married so I can not even begin to imagine what you are going through. However, I would imagine you are concerned about dating if a divorce does occur but this is probably not the biggest thing to be focusing on right now.
I don't think you need to begin a quest for a new partner with herpes. That should not be the common bond that holds a relationship together. Yes dating my be difficult but just as Backpacker has stated numerous times...it will be the person that is really for us that will be accepting of the news. Doesn't that kind of bring some level of peace to you. Knowing that a person will love and accept you no matter what.
My last partner's response after I told him I had it...was that stuff messes with your nerves! I laugh now when I think about it...basically my point is he didn't think loving me was worth the risk of something possibly messing with his nerves.
Trust me...he wasn't the one...but there are people out there that will want to be with you for you and won't mind risking a possible nerve irritation for the possiblity of true love...but let's not get ahead of ourselves...maybe your marriage can be salvaged...either way ...GOOD LUCK!
I think the key is to prevent and protect...and minimize the risk of spreading this to someone. Not to go around in solitude...marked for life.
