If she has been getting recurrent HSV2, any episode of sexual intercourse could carry a risk of exposing yourself to infection with HSV2. In order to lower the risk of transmission, she can be on daily anti-viral drugs. This will suppress the infection in her and lower your risk of getting it. These medicines are safe and effective.
The internet is full of information that is blown out of proportion. I have not seen any non-stop debilitating outbreaks in any healthy, immunocompetent person. Outbreaks are not physically debilitating after the primary(first) outbreak. Generalised malaise/ fatigue only appears in the primary outbreak. The skin lesions themselves would cause burning and pain in that localized area. That could be distressing. However, it doesn't stop you from carrying out your routine activities. Once the primary outbreak is treated with anti-virals, recurrences tend to be less frequent and milder. Recurrent outbreaks can stress out an individual but usually subsequent outbreaks are milder than previous ones and they tend to get rarer.
This is about how genital herpes presents commonly. I have given you the opinion you requested for and provided you with a clinical picture of genital herpes. It is up to you now to analyse if you can accept the risk and to take your personal decision. I hope my opinion can help you make an informed decision.
Please let me know if you have any queries.
