What makes you think you gave this to him?
Oral hsv2 is rare. When it does happen, it rarely sheds, and rarely recurs.
Shedding rates: (and you can find all this in the herpes handbook - https://westoverheights.com/herpes/the-updated-herpes-handbook/)
HSV 2 genital 15-30% of days evaluated
HSV 1 genital 3-5% of days evaluated
HSV 1 oral 25% of days evaluated
HSV 2 oral 1% of days evaluated

My question for you would be - if he did get it, kind of so what? You're married, you have hsv2, and now he does too, only orally. It rarely sheds, rarely recurs. Would it be any different if he got hsv1 from you? If he has any symptoms, he should avoid kissing people, but that's the same for hsv1 or hsv2.
You can't give each other what you already have, so now transmission wouldn't be an issue.
I'm assuming he knew you have hsv2, and he made an informed decision to be with you, knowing the risks. (If he didn't know, that's a totally different story with different implications for your marriage.)
But how do you know this is from hsv2, and not an hsv1 cold sore?
Can someone please post something. I'm going crazy trying to find any data on this!!
