If he leaves you because someone you were with well before he got in the picture got you infected, then he wasn’t the one anyway. If, however, you got this during the time you were dating, then that’s on you.

its not the end of the world. talk to a dr and be safe until you know for sure. but alot of people have it in one form or another. and there are many anti viral meds that can make symptoms short lived if you did contract it.

Hopefully he doesn’t have herpes and he just needs to know if you wound stay.

The chance of passing herpes on any given sexual encounter is pretty low. From men to women, without protection 2.5% with protection 0.13%. Though you really won't know if your in the clear until about 4 weeks after your exposure. If he's worried about exposure shouldn't be a big deal to press pause for a few weeks.
