The first thing I would do, if I really cared about the man, is get tested myself. LOTS of people have it and have NO CLUE. Really. Not saying the OP does. That's just a general statement.
I'm always interested in the people acting like herpes is the nasty cooties and getting all screw faced or running every which way as if gram negative bacteria infected fleas are after them--because the sad fact is that some of those same people actually have herpes and don't know it. They are completely asymptomatic and living their lives quite fine in ignorant bliss while they treat those with the same disease like they are disgusting people. Not saying anyone in this thread or on this forum has ever or would ever do that. It's just a general statement about something that happens in the world.
The problem here is it is very early in the relationship, so there isn't much pull to work through it. I certainly wouldn't ditch out on someone I was in love with just because they had herpes. I wouldn't end a long term relationship because of it, provided there was no dishonesty involved. But someone you just met or had a few dates with, that's a hard decision to make. This is why HSV positive people sometimes put off sexual intimacy and wait until later in the relationship to disclose their status.
Best advice I can give is to get educated about Herpes if it's really all that important to you. If he goes on suppressive therapy and you don't have sexual contact during outbreaks your risk of catching it is quite low. But it could happen. And like I said, it's hard to take that risk with someone you don't even know if you'll like in a few months.
There are message boards and websites you can go to and ask questions. "Shut up and Post" is one such site along with the personal website of the owner of that forum.
Good luck in your decision. That's a tough one.
