I [21F] almost died last night and my bf [20M] started arguing with me after the paramedics left

Last night some friends and I were getting ready to go out (my boyfriend had stayed at his place to do homework).
My best friend A [21F] and I went to the kitchen to get a snack, and shortly after I felt a large chunk get stuck in my throat. Before I stopped breathing entirely I managed to tell her that she needed to do the Heimlich maneuver on me. It took several attempts to get the food lodged in my throat out. I couldn?t breathe for at least 15 seconds. We both have first aid certifications so A started evaluating me after telling our other friends to go home. I was still feeling something in my throat and was very dizzy so we agreed that we should call my bf to get him over here in case I needed to go to the hospital. It took him 25 minutes to get here (he lives 5 minutes away). In the end, she called 911 because I was starting to pass out.
My bf got to my place right before the paramedics did and looked like a deer in headlights. He kind of just sat away from us not saying anything. The 911 operator had instructed A to monitor me closely and stay with me to ensure I was still breathing properly, as I was having issues. When the paramedics arrived, she asked my bf if he could open the door for them, but ended up getting up and going herself because he again was barely responsive.
Luckily everything ended up fine and I didn?t need to go to the hospital. After the paramedics left and it was just us, my bf started persistently asking if I was mad at him, that he was sorry and felt like a really bad boyfriend, like just a lot of emotional unloading. Obviously I was traumatized and the last thing I needed was to have to validate his emotions and comfort HIM that I wasn?t mad at him. He started arguing with both me and A saying that lots of people choke on things (???) and that A hadn?t properly communicated the seriousness of the situation (she 100% had). He also said that I couldn?t have expected him to show up right away, that he was finishing stuff he had to do. I kind of ripped into him despite my throat being sore and then went to bed. He kept asking as I was trying to sleep if I was mad at him.
We?ve been dating for 3 years. I don?t know what to make of this.
TL;DR I literally almost died and my boyfriend started emotion-dumping and arguing with me after about how it wasn?t his fault that he didn?t understand the severity of the situation.
