Yeah I’m a dude 25 and her 26 we’ve been together 9 years and have known eachother since 13 years of age I’ve told her I’m not gay and don’t want to date a man but she’s very adamant about this right now and I don’t want her to double down cause of my push back on the other hand I’ve been trying to accept it but I just can’t lol (btw she’s expressed that she’s unsure about surgeries and T at this point)
This made me sad.
Speaking as someone who lost one of the few partners I was serious about to trans cultism -- DO NOT under any circumstances affirm or accept her "as a man". You are not doing either of y'all a favor. You're hurting yourself with the self-gaslighting (you can't accept it because
she will never be a man and you know this; hell, it seems even
she knows this lol) and you're hurting her by enabling her descent into a cult. You love her, right? So stop that shit. Right now.
I'm personally one hair away from being irreversibly blackpilled on tranny shit concerning relationships, so my knee-jerk thought is to cut your losses and run. I know that's harsh, but when specifically concerning women with ROGD (which I'm assuming is what's happening with her?), the untreated mental illness that's causing the so-called feeling of dysphoria is often too strong for you to deal with in a manner that's helpful. At least, that has been my experience. If you go that route & bail, let yourself feel angry. Let yourself cry, and feel cheated, and lost, and all that sad shit. Don't run from those feelings, you need to let yourself feel them because she IS turning you into a victim by doing this, but don't wallow and let it destroy you. I HIGHLY recommend seeking out a therapist who hasn't been pozzed by the troon shit to help guide you through the pain. Think of it like lancing a huge boil -- it's going to hurt like all hell, but when it's over, you will feel better.
If you wanna go the

route and attempt to save your relationship, it will essentially only work if you can engage with her the way Aunt Carol suggested. You need to be able to have a gentle but firm and grounded discussion with her concerning the gender shit. No beating around the bush -- address things concretely as they are in reality. Keep a cool head, and try to talk to her in ways that engage her critical thinking/encourage her to ruminate on the underlying feelings that are the root cause of her ROGD. If you can encourage her to go to a NON-AFFIRMING therapist, this may help wonders and take the burden off of you. If not, I recommend looking into videos and books on how to kindly challenge family members who have become entangled in a cult, as all trans is is a body modification cult where a false (and ultimately unobtainable at that) image of the self is worshiped in lieu of a god. Find ways to get her away from her computer and her groomer friends. There are also some decent guides on how parents deprogrammed their daughters floating around on places like 4thWaveNow and many of them offer good advice for dealing with ROGD women of any age.
At the end of the day, regardless of which path you choose, I wish you luck. Do not forget to be kind to yourself.
