they think i'm non binary, but they still don't use they/them pronouns on me

Lmao but in all reality, depends on how accepting they are. When I came out to my mom I just walked up to her in a skirt, said surprise, and hugged her. She was pretty chill about it(I just can't wear them anywhere besides my early college school and friends houses cuz she's scared that the public might hurt me and she wants me to be safe)

But if they aren't as accepting or you're not sure I'd bring up the general topic and ask how they feel about it first.

I can’t say for sure as I haven’t even come out to mine (they’re 2 of the 4 people I haven’t come out to as trans yet), but if they accept you as non-binary, they should accept you as trans, but if they won’t use your pronouns, don’t expect them to jump to any sort of treatment

Just do it the same way as you did non-binary

I know this is weird. But there is a wikihow on coming out to your parents as trans. I’ll find it

That doesn't make sense
