HELP!! Idk what to do

Key
There is a guy that I've been seeing for quite sometime. We had sex once months ago and he is having negative but I found out I was hsv positive and I still have yet figured out how to tell him, I've just distanced myself from him out of fear that I would lose him altogether. Idk what I should do or how I should do it. I know I can not have sex with him again until I am able to be up front with him about it but I'm not sure of how. I don't want him to hate me for this 😪
