should've warned the girl about my STD

So on new year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> my boyfriend's friend came over and we ended up drinking a whole bottle of wine, some more alcohol mixed with other things and not long after ended up all drunk and really high on a couch cuddling and watching a movie after about an hour of watching it i started kissing his neck and rubbing her arm and long story short we had a threesome then went to bed, woke up, had another threesome then went back to sleep but the thing is my boyfriend was supposed to tell her he wouldn't have sex with her because we both very recently got diagnosed with HSV-2 but we got too shit faced and didnt tell her and now we dont know if she catched it and we should tell her or if she didnt and we dont need to the only thing sure is that we wont have more threesomes for a while
