The social stigma aspect is FAR to big of an issue to discount. 

1. A lot of places including many states in the US all but require disclosure. If you’re aware you have an STD and do not inform your partner and they get infected you can be criminally prosecuted. So disclosure is a must. 

2. For guys especially having HSV2 DRASTICALLY cuts your dating pool. It really doesn’t matter if this is due to stigma, misinformation, misconceptions, etc, the effect is the same, STDs are a dealbreaker for a huge number of people. 

3. Herpes isn’t always small potatoes, some people are much more sensitive to it than others. Some people only ever have 1 small outbreak, some people have frequent serious outbreaks that are very painful. 


This is a perfectly valid reason to end things and downplaying it is doing a disservice to OP.
