Gina, based on what I've read previously about your family's behaviour towards you around this issue they are intent on controlling and manipulating you, forcing you to conform to their view of the world. There's a good chance I will get a similar ultimatum from my father when I out myself in a couple more months and because he is the patriarch my mother would go along with it. It would break my heart but if they can't accept me as Grace then they cannot accept me full stop. Besides, they would find - as I'm sure your family would - that regardless of any mandate about presentation, the HRT will eventually make that option moot as you will look more and more female anyway...hair, face, breasts, etc. No clothing is hiding that! Those kind of ultimatums rob you of your right to be true to yourself. I know your family means a lot to you but if they cannot accept you being true to yourself then you'll need to decide what is ultimately more important to you. Hugs, Grace.
