What does your ex think about your intention to "out" her?
You call your ts ex-girlfriend a
boy
and want advice on outing her to your family and friends?
You do know stuff like that regularly gets ts women assaulted and at times killed?
I am in a relationship with a man who has introduced me to a wide range of people:
from his family and friends, to celebrities and several Heads of State.
None of them know my trans history.
He would never consider revealing my trans stuff to anyone else.
Your ex is better off never having any contact with you ever again.
Oh and finally,
You are soooooooooo not straight!
