AFAB genderfluid here. You have very limited information, I know that, but whatever.
My dad came from a quite traditional family. He used to be transphobic himself and was a little weirded out when I came out as a boy on some days, but my mom was always open-minded and my dad learned to accept it.
His sister, on the other hand, never learned to accept it and stayed the same: supportive of me liking men and women, but seemingly not supportive of me being genderfluid.
One day, I said I was on my period, and she said “Boys don’t get periods, so you’re a girl”. When I first came out, she said “Well I accept you no matter what my beautiful niece” and is always trying to get me to look and be more feminine. She tried to get me to wear a skirt a bit ago when I’m usually a guy, not a girl, and I also don’t really like wearing skirts as a guy.
I couldn’t possibly say from this post whether she genuinely cares about you or not.
But at the moment she is being blatantly disrespectful of who you are and how you see yourself, even if she is trying to help.
It could be she doesn’t realize she is being hurtful and could embrace you for who you are with a bit of prodding… and the other extreme is that she is someone who will never try to see your side, for whichever reasons have made this so ingrained to her.
I can’t know, because I don’t know her or her motivations. I may be naive but I trust that she does love you, even if she’s imperfect in showing it and maybe even if she’s a bigot.
Love is weird like that, and you can still love people who don’t understand. Hell, you can even love people you hate, but I dont think she hates you.
I think she cares deeply and is trying to help… and doing a terrible job of it, but she’s still trying, which would mean that she does indeed love you.
