I mostly go by their chosen name. She didn’t come out until I was 15 so it’s kinda confusing with the parental role thing sometimes. I refer to her to others as mother sometimes but usually not directly.

Then if I’m talking about my childhood I’ll often say “my dad” just cause that’s how it was in the memory, but then I immediately switch to feminine pronouns.

Might be some internal thing I should work on I dunno.
