I remain hopeful! At the moment he actually doesn't call me by either my old or current name. He just calls me "mate", and while that usually a thing guys in Australia call each other (meaning friend, buddy) it is also used between men and women, and between women to mean the same thing. So I'm OK with that. As far as I can tell he seems to avoid using pronouns for me at all when I've been around. He's received the message that I didn't appreciate being called by male name or by male pronouns, he's acknowledged that to a degree with some respect, but he's not willing to fully concede on the issue.
