We did have two weddings. There was a mass gay wedding taking place to celebrate the marriage equality ruling and it was a nice chance for her to get to be the bride, so we renewed our vows at it.
I think there's a misconception here. People seem to think that Lizzy was perfectly okay before she got the idea to transition and it's not true. Mental illness and substance abuse don't pop up out of nowhere. For the entire time I had known her she was interested in stereotypically feminine things and jealous of what she perceived as women having a better lot in life.
She discovered crossdressing, then came out as genderqueer. Iirc, this was around the time I miscarried our fifth child, so about April 2014. By June when John turned 3 she was identifying as bigender to me. By September she was out to me as a binary trans woman and had been through counseling about her gender identity. In October we started telling friends and family and she received approval from her therapist for hormones, then she never presented as male again except for job interviews. December was her appointment with the endo where she got the hormones.
Her family and I have had a lot of conversations about exactly what happened to change her so radically in such a short time. We all kind of feel like she got mixed up with people who reinforced being mentally ill and competed to see who could be the most broken. I think she was just trying to make herself feel okay but didn't know what to do.
