I don't know if this will sound really ridiculous and petty, apologies in advance.
I've been out as nonbinary for just about a year now, and I'm out to pretty much everyone I know. Then there's the topic of a friend of mine from college last year. I've sort of distanced myself.
I've been out to him for a entirety of the time I've known him. I've politely reminded him of things like pronouns and name
I remember when I was discussing changing my name and he didn't even take me seriously. He even made the odd joke about me being more girly than I let on. Because I wore makeup for a photo shoot. Because he asked me to.
He's not taken me seriously, the only slight accepting thing he's done is said he wants to take pictures of me in drag (I'm a drag king)
The last straw was a couple days ago. He had a party. Which turned out to be only three of us. Instead of not being a douche canoe and trying to respect my name and pronouns to a person I don't know, he essentially outed me by constantly using my birthname and female pronouns. The point of pronouns and name for a trans or nonbinary person is for their comfort. Not the comfort of the person talking to them. You might think it's because it takes him time to adjust. I've known him since last year. Like I said earlier, I've been out the entirety of the time I've known him, and changed my name not that long after I'd met him. Various other people have known me longer, years, since school, and even longer, and they seem to make an effort.
I've corrected him before and he made some form of excuse I can't remember what it was. But honestly if he has to make an excuse instead of correcting himself, there's something wrong here. I feel like I shouldn't be sorry for correcting him as my name and pronouns are there to make me more comfortable. I shouldn't care about the comfort of other people seeing as it's my name and my identity and other people shouldn't be ignoring it like it doesn't matter.
Not gonna lie, whenever this particular person mentions my of birthname, it sounds like he doesn't take me seriously, that he feels like he decides what my identity is, and that he knows my gender better than I do.
I've been searching for similar stuff on the internet but I can't find anything that gives suggestions with what to do with the people who misgender you even though you've reminded or corrected them before.
