Did I get herpes from my boyfriend? We've been having sex for months and I just had my first OB

I am so confused. I was recently diagnosed and I'm freaking out about talking to my BF about it. We have been dating for 6 months and I saw him a week ago (long distance relationship) and a day after the last time we had sex I started getting symptoms - blisters on mouth/vagina, fever, chills, body aches, etc. I've been reading so much online which I know probably isn't the best idea but I'm so scared. Does this mean he has it? I read somewhere that I could have gotten it from a previous sexual partner (would have been over 8-10 months ago) Is that true or false? Also I'm so scared of telling him and he never wanting to have sex.
