I ghosted my best friend after he came in my mouth

I (18M) and my best friend (19M) had planned a hang out for months. We were going to be band boys for the day, I was gonna pick him up play some guitar, play some bass on his guitar, play some video games, and just have a good time. I had to discuss one thing before we did all this, don’t come in my mouth. He already knew this but I reinforced it. I didn’t need a repeat of what happened the last time we hung out. I had nasal cancer scare that sent me into surgery and a PET scan. We finished discussing that and of course he said he understood. We went about our day, played some Halo, played some bass on his guitar, then played some guitar on my own. Until later, once night started to fall and we were bored of the already stated activities. We went to play some more Halo. But before we did, I asked if he wanted a sip of my soda. He took the soda, opened it and started chugging. Then turned the soda down on the coffee table and left. He said “You’ll be the judge of whether or not I came in your mouth.” Then left. I thought that was a pretty weird thing to say. But I didn’t think much more of it. But I got thirsty and I was like, “shit I’m not drinking that soda.” So I left the soda on the table. The next day, I got extremely tired, nauseous, and I had a shit ton of pain in my nose. I didn’t quite remember what it was, but I immediately left for urgent care. I couldn’t breathe anymore. They did some tests and it turned out that I had gonorrhea of the sinuses. I almost cried. I looked it up online and it seemed like a really long drawn out process. They sent me to the emergency room, which in turn sent me to the hospital. I waited 4 hours and nobody called me. I called the urgent care and they said that they forgot to fax the information over. I was pissed. But I waited another 4 hours and finally they called me back. I went in and they said I needed to take antibiotics. And I said that’s fine. They said not just you, but your best friend as well. He was my best friend up until that point. He had just given me a disease that could easily kill me. When I got home and was alone, I cried. I was so upset. I had never been in a worse mental or physical situation. I was given the prescription for the antibiotics, and rushed out of the er, as they had already forgotten about me twice. I had to take them for 5 days in total. I was finished with my friend at that point. I got out of the hospital and called him immediately. I was so mad and upset. I told him that I was going to be busy the next week, and that I didn’t want to talk to him. And that’s when he told me that the reason why I got gonorrhea was because he couldn’t wait and got himself off in my soda. I was so mad at this point. My best friend just tried to kill me. I never thought he would do that. And I never would have expected he would touch my soda that way. I couldn’t drive to his house and strangle him, so I just hung up the call. The days went by and I was just trying to fucking survive at this point. I had to get blood draws done and drive to the pharmacy 3 times. I couldn’t drive and I was in and out of consciousness the whole time. It was one of the worst experiences. I finally finished taking the antibiotics and I was feeling better. So I went to hang out with him. We went to his house and we hung out there. He was like his regular self, but I was fuming in anger. He told me that he loved me and I felt sick, and I said “I don’t love you anymore.” He was confused. I told him that I was talking to other people and I’m not sure if I want to hang out with him anymore. He got mad at me and yelled at me, and got up in my face. I told him that the reason why I was acting this way was because he gave me nasal gonorrhea. And he was like, “what do you mean?” And I told him “do you remember you came in my soda?” And he said “oh yeah I did that.” Like it was nothing. And I said “so why did you do that?” And he told me “I thought it would be funny.” I was so mad. He thought it would be funny to give me an sti and possibly kill me? I stood up and I told him that I didn’t know if I wanted to be friends with him anymore. He was confused and told me not to go. I told him that I was going to go sleep on it and when I’m done I’ll call you. He said “that’s fine.” And I left. And I never called him. I never texted him. I never told anyone that he was a piece of shit. But tonight I’m telling reddit. Previously my best friend, now my ex best friend, for trying to kill me, and giving me an sti.
