My partner says I'm ruining our daughter's life because I don't want to be called "mama"

I'm 19 and nonbinary(AFAB), my partner is also 19(M). Our daughter is around 10.5 months old and even while I was pregnant I HATED being called a mom. It gives me intense dysphoria and it takes everything in me not to start crying when people call me a mom/mother. I did some searching and found a lot of neutral alternatives, originally liking the term baba, but a lot of my family pointed out that's usually a baby's term for bottle or brother, so I eventually settled on "mapa", a mix between mama and papa. My side of the family (except my grandparents even though I always correct them) have been super open and vigilant (is that the right word?) with using this term when referring to me, especially around my daughter, and quickly correct themselves if they mess up by accident, though it's become less and less frequent as time goes on. Even our advocate from the local teen parenting program has been calling me mapa when talking to my daughter. My partner, on the other hand, made it clear from the beginning that he thought it was stupid, even after I've explained to him over and over how being called a mom makes me feel. He also never corrects his family when they call me a mom or say mama when talking to my daughter, especially his grandpa who we live with and is at the house for a week or so every month who is ALWAYS saying it at least 5 times a day while pointing to me. My partner has begrudgingly accepted it and will call me "mapa" when talking to our daughter, but is always "accidentally" messing it up and gets upset when I correct him, even though he is extremely supportive of my gender identity in every other aspect. Our daughter has been saying "dada" for about a month or 2 now and I've been trying to teach her "mapa" as well. She's gotten really close with "maba" as the p sound is a more complex sound for infants, but I still praise her every time. Well, two days ago I was sitting on the floor with my daughter and repeating "mapa" while pointing to myself. She said "maba", so I clapped for her, gave her a hug, and praised her for it. My partner was sitting in the recliner watching tik Tok and he spoke up saying I was confusing her and making it more difficult than it needed to be by having her call me mapa. I asked what he meant and he said that with other people calling me mama(only his family), me trying to get her to call me mapa was just confusing her, and he also mentioned that she'll likely get bullied in school because she doesn't have a mom, but has a mapa. We got in a huge fight about it, where I told him if he would just correct his family it wouldn't be as much of an issue. He said we can never celebrate mother's day, she'll get bullied, she'll be confused, and that she may even resent me for "forcing her" to call me mapa and ruining her life. By the end of it, I was crying and felt like a horrible parent. As someone who experienced a lot of bullying in school for things I couldn't control, I don't want to subject my daughter to the same thing, but I CANT STAND being called mama/mom. I don't know what I can do anymore. Am I really ruining her life?
