well, I tested negative but then came up positive a year later although I know for a fact that person was infected although the test was negative... I don't know best wishes to you hope everything is ok. I really hope a cure is discovered in this life time.
you both need to check to see if you were actually tested for herpes or not when you had your testing. it's typically not a part of routine std testing so both of you call and find out and then go from there. if either of you weren't tested, you want to get type specific herpes igg blood testing done to see who has what.
