I had a very difficult relationship with all of my family.
They knew what I am. Even though it was never spoken of. It's kinda obvious for those that know me really.
But I know, if I had ever tried to talk any of them, each would have turned it around to be about them.
My father would have seen it as yet another excuse for his own failures. My mother would have seen it as yet another problem in her life, everyone is blaming her. My sister would have seen it as me invading her terrotory. My brother, well, he would probably have used it as an excuse to attack me again.
Sorry, if this isn't quite what you wanted. But I do sympathise.
I walked away. Form all of them. Never looked back.
But one point I will suggest. If you start trying to avoid doing or saying things because they might question your identity, then you're being as fake and dishonest with yourself as they suggest you are.
If, for example, you like fiddleing with car engines, watching sports, drinking beer, getting into fights, listening to whatever, none of this makes you anything other than someone who does these things.
Who said a girl can't do these things? And who put them in charge anyway?
