Herpes...

So i've been talking to this guy for a week few weeks we had sex 2 times and he texted me today "oh i forgot to tell you I have herpes". I had asked him before if he had anything and he told me no I know asking isn't enough and I'm acknowledging the mistake I've made. Yes we had unprotected sex which freaks me out even more. He told me he takes medicine to decrease the outbreaks of the herpes so i went to the doctor as soon as i got the text and they told me I can't do anything but wait to see symptoms but they tested me for everything else. I asked the guy i was talking to why he didn't tell me before and his response was "im an asshole i really don't care". The even worse part about this is I had sex with someone today not knowing I was exposed to herpes and I'm not sure how to tell the person what's going on. I'm currently numb right now but still very scared i know this waiting game is gonna kill me. any advice would help I don't know what to do right now.
