HSV1? Freaking out

My boyfriend just called me and told me he got a call from his dr today and he has HSV-1.

I’m like.. kinda stuck, don’t know what to think, do I need to get tested? Did he cheat? He said he hasn’t had any outbreaks or symptoms ever but I’m wondering like what made them even check for it? 🥴

Anyone have any knowledge on this?
