Long-standing close relationships seem to have a different set of rules and options. I will always call my husband by his birth name, and as husband, he/him no matter how female his body eventually appears. Just as I will always be his wife/she/her, never they/them/ze/him, even if I go through bottom surgery. My husband told our kids that he is still dad to them, and I will be mom, and both of us rejected our younger son's gender pronoun offers. This whole gender pronoun changing thing has always made me uncomfortable. Maybe we're just too old and set in our ways to change? I don't know.
