Yukari-sensei,
There are two things that I have done around that issue:
1. I made a promise that I would present as male through the summer and the fall up to my nieces wedding. I was there, I did what I needed to do. Now, however, there is some panic and some push to keep being HIM. I'm pushing back, firmly but also gently.
2. My wife supports me fine sometimes and then blasts me out of the blue. She started using female pronouns this weekend. We went shopping together. We had fun. Then, last night, she called me "A big, handsome man. I repeat, MAN." I just stared at her, trying to figure out where that came from.
Even when there is support, sometimes, it's hard on them. I try to be understanding but firm. Unfortunately, I really don't know if it is working. I also think I need to talk to the "problems" more. But I just keep plodding forward, then, if necessary, an agreed upon pause, then back forward. Always, telling them how I love them. Best I could figure out.
Hugs,
Jen
