I have a friend with DiD

I don't even know what to tag this.

I have a friend who I met as a nonbinary they were kinda the stereotype theyfab fujoshi 15yr old tumblr girl in a grown woman's body but after a conversation that wasn't really all that deep to me but supposedly identity defining for him about how he feels with his relationship to two boys kissing he realized he was a trans man.

it wasn't a good look from the start. he was hyper fem even as nonbinary, likes men, piv, very 'fembrained' but also says he hates these things about himself at least the fembrained stuff. So I as a trans girl kinda took a step back from my own stealth life to kinda do some mulan-esqe training on how to be a man. I see potential but if I wrote a resume about what I'm starting with we've made theyfab/pooner stereotypes here that are less accurate to themselves then he is.

I dont want to start dragging anyways, this friend has DiD and from what I understand a new 'alter' has sprung up very recently and supposedly partly due to me. This alter is 'entirely male' and is the 3rd of two others (including the one I am friends with) who he (the alter) preceives as women entirely. This new alter misgenderes the other two and almost every single sentence referring to them starts with "those whores, those bitches" This masculine alter is very transphobic to its own host and also sexist to everyone else. its like a manifestation of masculinity if it only learned masculinity from johnny bravo. Its always talking about sex or objectification, if its ever talking about a woman its measured on the womans sexyness. I'm apperently exempt from it because "I'm sexy"

I feel to blame for all this. I was told that it was from my trying to rear him into unlearning his femininity that in part is due to why this persona manifested even though I never taught this kinda stuff. I told him (the alter) that being a man is more then just puffing your chest and talking about sex and that "he understands manhood like a boy, not a man" and he (the alter) crashed out.

I don't know anything about DiD, sometimes I think I got it but I'm not even sure. But I just needed someone to talk to about this and maybe know what is going on like does this sound real or is this just tumblr crap?

I wonder how that effects GD. He has an alter that is supposedly entirely cis female that isn't feeling so great about the transition but is willing to step back from ever being at 'the helm' of this body. then when this male alter took over for the first time I spent almost an hour spiraling about being in a female body and feeling all these senses and stuff it very much didn't like. In this case are they only 2/3rd trans? are they simultaniously trans and cis depending on whos in charge at the moment?

This is all fascinating and terrifying to see as a observer.
