Personally I feel being confronted by it like that wouldn’t work out well for me. I tend to panic in moments like that and forget to say all of the things that were most important to me and the situation. It makes sense why you did that for her and it sounds to me like it was a good thing, however if someone in my family did that I think I would dip out and put the conversation on hold until I could prepare myself. Coming out as trans requires a lot more explanation and detail so I’ve been writing everything down in a notebook that I will fork over to the people I want to tell. I think that’s easier than trying to organize a face to face conversation in which all of the things I want to say will inevitably fleet from my brain and I’ll have no idea what to say.
Honestly my family is incredibly hard to decipher. Maybe it was that way for her, she didn’t know how you would react and had no way to predict it.
its definitely possible, I look back at myself when I was a kid and I realize how obvious it was. I just didn’t have the language to describe any of those feelings. I do think they suspect something right now, there have been some offhand comments hinting at suspect as well as encouraging things said to me, but it’s all a mix of good and bad and I can’t predict their reaction when it’s given to them straightforward.
