Situation is an online one, where some 5 years ago I had a sideblog Tumblr that occasionally mentioned I was trans for support reasons. Later I deleted all the trans references, and continued using the blog in a different community. Fast forward to now and that blog has been deleted, but a friend "helpfully" found it for me on the WaybackMachine, which also just happened to include a saved post where I mentioned I was trans at the time. I do not identify as trans and do not ever tell people I am trans. I just identify as male, and have pretty much since I transitioned in 2008 but sometimes especially online, I used to say trans/FTM just for the sake of clarity. As I'm doing now.

Anyway, this friend just messaged me like, 'YOU NEVER MENTIONED YOU'RE TRANS' and I don't know how to respond. My initial reaction is "obviously there's a reason for that" and "it's none of your fucking business" but both of those answers would 'admit' that I am trans, which is not something I want to do. My other option is just to ignore her message/not respond to it at all, but that may lead to her asking again and being more admission by silence. And I guess in the end the 'secret' is 'out of the bag' so to speak... In other circumstances I would 100% cut this person out of my life, but unfortunately we run an online community together, and to do would would mean I'd have to leave that entire community, which I am not willing to do. sigh.

Any advice is appreciated.

Also I may delete/edit the text of this post later in the event she somehow stumbles across it, even though she shouldn't know this account at all.
