The problem with spouses/family/friends "missing" parts of the previous you they knew is that when you give that to them, you are keeping a ghost alive in their minds, a ghost that allows them to misgender you. Maybe not out loud, but in the pattern of interaction with which they were previously comfortable, and almost all of these patterns have subtle gender implications.
For me, at least, that was completely unacceptable.
Especially with my voice, because voice is highly gendered. I will not, and have never, pulled out the old voice to comfort someone. As if it were a party trick? I refuse. No, if someone couldn't fully accept the real me going forward, there was no going forward. And if someone's longing for something like voice, that's a huge red flag.
