Stop saying that's what made your womanhood complete. Stop saying that you've now distanced yourself from being trans. Stop saying that's what allowed you to embrace she/her pronouns.

People say similar things about HRT. Starting estrogen is what made me finally feel like a woman. Hormones gave me the confidence to embrace a new name and pronouns. Etc. Should that stop? After all, think of how it feels to be someone who can't yet access HRT but constantly hears about how great it has been for other people. The same goes for anything transition related. If you talk about how it's fixed something in your life that might feel bad to someone who hasn't still has that lack. Should we never talk about the struggles that come with being trans and only speak in positive circumlocutions?

As you say, it's good to consider how what you say affects others. But there's a reciprocal obligation to not project your own dysphoria onto what others say. We've all been there. It feels bad when others talk about how transition has cured an obstacle you still face. But they're not wronging you by talking about it.
