My ex, although she has always been very supportive and treated me as myself, was really emotional at the thought of me losing my voice. She didn't care about my boobs going or me having a penis, or about being seen as a straight woman, but the voice really bothered her. Even though she knew it had to happen for everyone else to see me as male, she already saw me for myself, and to her, my voice was like...you know, the voice that said "I love you" and so on. I remember when my voice finally dropped into the male range. We had been broken up for about a year and a half, but I sent her a video and she admitted that even then, it made her emotional to hear that my voice was gone. She was, of course, happy for me, but it was hard on her.
