My partner of 3 years keeps calling me a dense cunt?

So my partner of 3 years and I were talking about our upcoming vacation days and I mentioned that there was a potential opportunity for me to meet up for a quick meeting for a new fulltime job (im currently on a temp only job) on one of our planned days home, but only if he was okay with it as it is our shared time off. To this he then responded with "that is going to fuck over the entire vacation." And I then accepted that this week was not going to work, and said that I would tell the person who was trying to set up times, that the ones provided wouldn't work." My partner then proceeded to get upset and say things like you dont understand, why do I even bother, and things like I should just work instead. Which I was really confused about as I had just agreed with him and told him how I was going to handle the situation. He then continued on about how I just didn't understand, so I asked him to please explain what I wasn't understanding, and then he started calling me a dense cunt. The name calling happened on our entire walk home anytime I said something to him, I got told I was a dense cunt and I would ask him to stop calling me that as it didn't make me feel respected and he said oh well you are acting like one. And then as we got home he proceeded to tell me how I was being dense and more of a cunt. I kept asking him to stop, and asked why is this fight even happening, to which he said I never listen, and that because I couldnt remember what we had discussed an hour earlier while I just got home from my job (I also have a processing disorder), he expected me to recall and tell him exactly what we had said earlier or gtfo. Until he finally pushed the pizza we had gotten for dinner at me and said I can't even be around you sleep on the couch. And then told me he has had a ring in his pocket during all our fights but I dont deserve it. Im starting to feel like I can never figure out what im doing wrong or what I did to make him hate me so much.
