She might have it but be asymptomatic, which is the case in most people who have herpes. She should get a blood test, which will tell her if she has it even if there is no outbreak symptoms.
Tell her to get her doctor to order a type-specific blood test, preferably the Western Blot test. It's a bit pricey compared to others, but it's considered the most reliable/accurate of the blood tests and will determine type-2 versus type-1.
Sorry to hear of your pending divorce.

Good luck to both of you.
