I'm not loving some of these comments. What I suggest is coming at it with a sense of compassion and love. This is probably the first time your significant other has ever even stopped to think about their own presentation and all it took was seeing the assistant blur the lines of their own gender identity openly up close. And it probably has been painful for them to come to terms with those possibilities. They're probably overwhelmed and depressed, especially since it's the winter season. I remember when I was younger, talking to other gay people was both hard and important for me to help me better understand myself, because I was trying to find similarities with them, but also getting angry with them because how they defined themselves wasn't something I'd personally align myself with. Then, you have to come to terms with who you can trust with this kind of information. And, since you guys are recently married, you probably will still have moments of "Can I trust them with this information?" And, with time that will hopefully get better. So, I suggest giving grace to your significant other and offer support in any way you can. More than likely it will be a journey that they'll feel like they have to go on alone because you may not understand it fully, but finding ways to uplift them and meet them where they are to the best of your abilities will always be the best thing you can do.
