Family issues

I had came out as a transman in 2014 & although some of my friends and family were more than supportive, some were not.

if any random were to pass me by in the streets they would not even second guess me, as I look and sound just like a biological male. no one knows unless I (feel comfortable) tell them. due to my own personal reasons, I don’t tell anyone (although my fiancé of two years know because it was only fair I had made mention of it when we started out dating)

my issue is, my sister feels the need to still tell people my business. my brother in law and his wife know because my sister can’t help herself but run her mouth about me. I can’t say anything to my sister because she’s a nasty person at times and I don’t want for her to ruin my brother in laws wife’s business. it’ll cause issues within both families if I say anything. BUT I want to confront her about telling people. I don’t like anyone “new” coming into my life to know my business- my past or “old self” because I never identified as that person. this is who I am - as I am now - how I should always have been.

any ideas on how to get out of my own head about it all.
