Boyfriend making ignorant comments about my diabetes, feel like I’m losing my sanity

I am in a 4 month long distance relationship. I was very close friends with my boyfriend for about a year before we got together, so I am astounded by his comments. We often have arguments and if he has upset me, I try my best to calmly explain why. But he never gets the whole picture, he keeps asking the same question over and over and over again, as if I had never tried to explain anything. I am even considering whether he has some kind of communication disorder, he has also said he struggles to translate his thoughts into words.

I was very irritable and anxious, I was on the bed crying because I felt so anxious and couldn’t leave the bed even though his brother announced that dinner was ready, my boyfriend got annoyed telling me that I was being a rude guest, he left to go to the kitchen. Next thing my Dexcom says I’m 2.5 and going down, I have glucose and sent a text saying that I’m very low and to start without me. 10 minutes go by and he didn’t even come to check if I was ok. After I felt well enough, I told him that I’m upset that he read my text that I was low and didn’t even bother to come and see if I was ok, for all he knows I could’ve been on the floor having a seizure. I said that I was behaving strangely because I was low and it wasn’t my fault. I said I wanted to go home because I felt unwelcome, to which he said that me going low was my fault, and that I can pack my bags and leave by myself to go to the airport. I asked him why is he being so mean, and I proceeded to have a panic attack because I felt unsafe. His brother came and helped calm me down, and told my boyfriend that he was too harsh on me.

He recently has said “remember to take the right amount of insulin”, which I calmly explained that it is an unhelpful question because it’s not as if I choose to not take the right amount of insulin. He proceeded to say “I don’t agree”, which made it 10x worse, and has repeatedly asked why is it offensive even though I feel I have explained about a million times. He then asked if I wanted him to agree with me in any case, which was incredibly frustrating because out of the whole time we have known each other, I have always said that I don’t expect or want people to agree or disagree with me, I just care about whether the topic is being discussed in a mature way and that everyone’s view point is taken into equal consideration. I made a lot of effort to try and explain how I manage my diabetes and how I’d like to be supported, but he, 4 months into our relationship, does not sound any better than some stranger making ignorant comments about diabetes. And this makes me very upset because I cannot imagine a future with someone who doesn’t want to make the effort to learn about my diabetes management, and therefore makes me feel unsafe around him if something bad were to happen to me.

Nevermind about the diabetes, I feel that he often doesn’t take my feelings seriously or listens properly. I was crying and describing my past emotionally abusive relationship, and he started having a laughing fit because he heard “fart” out of “... far too ...”. I asked him to stop laughing his ass off and he just laughed even more. I was really upset.

I would write more but then it would be too long to read. I need someone that isn’t involved to give some perspective, because I feel like I am going crazy and don’t know what to think anymore. Thanks for reading.
