Okay, this is going to need a LOT of context. My (18f) bf (18m) and I have been together for almost two years now, and overall our relationship is pretty good.
Recently, he's been making fun of one of my serious interests, this anime I really like. For context, I'm diagnosed autistic -- I'm going to have deep, strong interests like this. And because of that, they mean a lot to me, and I have strong feelings about them. It started as him hating on my favorite character, which, okay, whatever. He's not for everyone. But this kind of upset me because this character had made me feel seen at a period in my younger teen years where I was severely suicidal and felt completely alienated, and when I told him this, he told me that it was weird and unhealthy to see a fictional character that way. Fair, maybe? I'm not sure.
It keeps going. He starts mentioning all the things I do that relate to this show. My wallpapers, my bag keychains (one of which HE got me), my fanfics, my social media feeds, my taste in books (the characters in this show are based off of real authors, so id started reading some of their books, because I wanted to get into classics anyway). I actually found my favorite author doing this, and have read his most famous book countless times. It was the only time I'd read a book that made me feel like I wasn't completely alienated from other people. It really comforted me. He knows that, too, yet lately he's been absolutely dogging on the author and saying how his writing is shit even though I emulated my own writing based off of said author (which he also knows). When I brought this up, he got defensive and says he loves my writing.
About that. He tried to read my fanfic, when I specifically told him I didn't want him to, because the last time he did, he just laughed. (And not at parts that were supposed to be funny). This isn't about if I'm a good or a bad writer. It's the fact that he's making fun of his own girlfriend. He started reading again, and later quoted all the lines he found bad or cringy, even though I asked him to stop multiple times. Then when I actually got angry angry, he got mad and said that id been pissed at him all day and he was tired of it. He proceeded to tell me that my obsession with this show is weird, unhealthy, and makes him uncomfortable. I said I was sorry, but I feel like I shouldn't have to? Why is he making fun of things that make me happy, my interests as a neurodivergent person? He won't budge.
