Hsv1....am I guilty?

So I just found out I’m HSV1 positive. My non exclusive partner asked me to get checked. Of course I did bc I’ve only had two other exclusive long term partners in my life and I’ve never had any signs of anything. When I got the result I’m devastated. I don’t ever remember having cold sores. From my reading I’m guessing I, like the majority, got it at a very young age. I’m assuming I didn’t get it from him bc I haven’t had an “initial” outbreak.

ANYWAYS now he’s saying his other partner is experiencing symptoms of herpes in her vaginal area. He said he’s never been tested before and I know he’s had quite a few partners. So my question is....if I’ve had it a long time how come NONE of my partners including my current one have never told me or shown any kind of initial outbreak.

Isn’t the “initial” outbreak the worst?! I’m so confused and Idk if I should feel guilty or not for potentially passing something to someone I don’t even know.
