Cold sore VS herpes

So my bf and I were suppose to go on a trip but had to delay it because of his cold sore. At first it didn't concern me because I thought it was just a sore, not an STD or anything 🤔🤔.. until he started to complain about how much pain he was having and how it wasn't going away. So I started to google what a cold sore was exactly. Long story short it's a strand of herpes. He's been getting them since he was a kid so I wasn't too grossed out. But now it affects me. Im scared. Even though it's not genital herpes. It's a strand and 8/10 people have it. Some stay dormant (never to appear) some have it activey. does anyone else have this dilemma in there relationship?!? Help me out!
