herpes.. should i tell my boyfriend?

Hello. This is my first time posting a topic on forum so it might be hard to read but I'll try to organize my long story.
Anyway, I lost my virginity 3 weeks ago to my first boyfriend who is 28 (I'm 1. On that night, I ended up having sex twice unprotected . It happened so quick that I totally forgot to ask him about condom and the next morning I finally realized that I'm in trouble .... I was disappointed of myself because i thought i was mature enough and knew enough information about sex.

From then on, we started to have sex every time he comes visit my house ( twice a week).but stupid me, I always get overwhelmed and end up forgotten to ask for a condom , I felt like I completely missed the timing to ask him for it....
I was worried about getting pregnant, but I had no idea about STDs...I was screwed at this point but 2 days after I had my last sex a nightmare happened I felt a cut in my vagina, it started to itch and burn... so I made an appointment a clinic for check up and I was told that I was diagnosed with herpes..

it is obvious that I got it from him but I am not mad at him nor devastated about herpes actually, although it hurts like a hell I can't even walk. but I don't know what to do with my boyfriend. I need advise!! any advise it'll be appreciated ! because I am amateur on sex, boys, life, love etc... Thanks.
