My partner wants me to compromise if I transition, support group encouraged him to push me to compromise

So I joined a TGNC support group recently, and it has been so incredibly helpful for me on my journey. I myself identify as Trans Non-Binary (ftnb) and have recently been considering top surgery. My partner does not want me to do it because he doesn’t know if he’ll still find me attractive. We are married and I understand his concerns, but he is pushing me to consider a breast reduction instead. I told him that’s a big compromise and that I don’t feel comfortable with the idea. As my dysphoria quelled, so did the topic. The center that I go to also offers a support group for partners at the same time that the TGNC meeting meets, and given the difficult conversations we’ve had, I urged my partner to go and he agreed. When I got out of my meeting and went to the other room to rejoin him, he seemed elated and thanked the two running the group over and over, which made me ecstatic that he seemed to find solace. After leaving however, he kept misgendering and deadnaming the woman that led the group, saying that she told him to call her Tom to avoid confusion (that seemed to add confusion but do you?). My partner went on to say that her girlfriend was there and was saying stuff like “what about me?” in response to “Tom” wanting to transition. Because of this “Tom” has put her transition on hold for the sake of the relationship. To me, this didn’t sound like the best pair to be running the meeting, given their situation. THEN, my partner goes on to say that he brought up me wanting to get top surgery and then girlfriend piped up with “what if they just get a reduction?” to which my partner, feeling validated, replied “that’s what I said!” This is not what I wanted him to get out of this experience. What works for others may not work for some, but to encourage him to push for me to compromise on the choices I make about my body has me floored. I felt bad saying this, but I told my partner that no relationship is more important to me than the relationship I have with myself and my body. Am I wrong to be upset and not want him to return to that support group, even though he enjoyed it? What should I do?
