So first, you probably mean HSV - herpes simplex virus. HIV is an entirely different illness.
You definitely have hsv1. Your number is high enough to be a definite positive, and while you probably didn't get it from drinking after someone - we know now that's not an efficient way to transmit it, it doesn't really matter. It's a very common virus - 67% of people under 50 have it globally.
Your hsv2 test - why did you test for that? Do you have symptoms?
Lower numbers can often mean a new infection, but it doesn't always. Unfortunately, there's no way of knowing when you got it from a blood test.
Your spouse's hsv1 test, by the way, can be a false negative. The hsv1 IgG misses a full 30% of infections. The hsv2 test misses 8%, so it's not as likely that their test is a false negative.
There are false positives on the hsv2 test, though. If you've had symptoms, it's far less likely, but I'm interested in what your symptoms were.
