A virgin does not have HSV 2 unless they acquired it at birth or they had very intimate contact that didn’t include intercourse but did include lots of genital to genital rubbing. and if your daughter had contracted herpes at birth, she would have been sick sick sick normally speaking.
You did not infect your daughter and thus she did not infect her new husband. I’m not sure how to help you get past this but you do need to. Genital herpes is simply not transmitted from parents to children. It’s just the truth. I’m so sorry this has bothered you all this time.
