Well, if I were you I would totally tell him. It is important that he knows what he has and gets tested, that way he can be more careful in the future and avoid transmission to other partners. It's true that you can't stay mad at him forever and I thinks it's very mature from you to put the cards on the table, it's the right thing to do. You don't have to accuse him, you just have to hit him with the facts, I think handing him your test results is a good idea, that way you can see how he reacts, maybe he knew he had it, maybe he didn't. When you dated a few months ago did you guys use protection?
I got it from someone who knew he had it but "thought" nothing would happen to me because he was asymptomatic at that moment.
Best of luck!
No, genital HSV-1 transmission from genital sex to an uninfected person does happen, it is rare in its own degree. It happens to about 1% of couples in the discordant situation described each year.
If your partner suggests he didn't know he had genital HSV-1, then I'd suggest he told a porkie pie!
This compares to the 0.0001% or lower annual chance of reinfection! So no, there is no need to feel sad at all.
You also seem to make out that having HSV-1 is some form of death sentence. It is usually the opposite. The cohort of people with HSV-1 are as healthy if not more so than those without HSV-1 and have similar or less morbidity (aggregate symptoms, pains etc.) than those without HSV-1.
There is nothing impaired about a person having genital HSV-1. No shame, concerns, health deficiencies etc.
No fate but what we make! Choose a good fate!
