I'm sorry you're going through this. I really hope you're in the US, because figuring this out otherwise is going to be tricky, and next to impossible otherwise.
First, let me say that we know now that some people get false positives on the hsv2 IgG, which it sounds like you know already. Most of the time, it's results under a 3.5. However, even those with results over a 3.5 who have no symptoms can have false positives, and yours aren't that far over that. If your results were like 11.8 or something, I wouldn't be mentioning this, but it could still be a false positive.
So, what now? You need to get a Western Blot test. This is where it gets tricky, or it could. It will likely get expensive. There is no right or wrong answer here, okay?
The Western Blot test is different because it looks for different proteins, and is considered the gold standard in herpes testing. Your doctor can order it, though many (most) don't understand this process, and most I've talked to here in these forums really struggle to get their doctors on board. If you have a good doctor, and good insurance, give it a try.
If that's not the case, you can get it from Terri Warren, who is a nurse practitioner, and one of the world's leading experts in herpes. You will have to self-pay, though, and it will easily run into the several hundred dollars.
I don't say this to discourage you at all - if you can do it, I think you should - I just want you to be prepared for what it will entail.
I can't tell you if you have hsv2, or even the odds. A test result under a 3.5 has a 50% chance of being a false positive, and a 1.6 has probably an 85% chance. We don't really know the chances over a 3.5, and yours are really not that much over.
I would suggest setting up an appt with Terri Warren, and if you can, get the Western Blot. I'm not a doctor, but I'm not convinced you have hsv2.
The hsv1 IgG misses about 30% of infections, so it's more likely that you have that, but about half the adult population has that, and it's probably an oral infection for you, and that's not a big deal.
You can read more about all of this in the Herpes Handbook at https://westoverheights.com/herpes/the-updated-herpes-handbook/ It's free, and you can read it right on your phone or computer.
Please let me know what you decide to do, and if you have any questions. Hang in there, okay?
Forgot to add, the 4th test was Aug 1 and the 5th was two days later.
