This means that you have herpes type 2, and it's genital.
Your doctor may have told you that this means you were exposed in the past, or that you were a carrier, but there's no such thing as a herpes carrier, or just "being exposed" if you have antibodies. (AB stands for antibodies. Once you are infected with something, your body creates antibodies to fight that off. The hsv2 IgG test looks for hsv2 specific antibodies.)
This means that you can get outbreaks, can shed the virus, and can transmit it.
Have you had symptoms? What made you test?
You should read the herpes handbook, written by Terri Warren, one of the world's leading experts on herpes. It's free, and you can find it here - https://westoverheights.com/herpes/the-updated-herpes-handbook/
If you let me know your gender and the gender of your partners, I can give you transmission stats. It's probably not as high as you think.
I've had hsv2 for 15+ years. It's really just been a blip in my life. Finding out I had it and dealing with the initial acceptance was the hardest part - the rest is really pretty easy.
Let me know what questions you have, and I'll do my best to answer.
