I watched Being Chaz.... He ask her to sign a prenup stating that she would not drink anymore. She told him that she just couldn't sign it.
Maybe some time apart will help.

why didnt he want her to drink anymore? Is she in recovery? Or is he asking for his own reasons?

She is a acoholic...but it seemed like , maybe when she gets really stressed, she falls off the wagon.

My initial reaction was similar but then I think of my own plans to transition (male to female) and how it sadens me that from my mothers perspective, her loving son of all those years will have disappeared as my voice and face is feminized. I respect these feelings my mom has. I understand that there are costs to transition but in the end it is more important that I express and present myself as I have always wanted to. She knows I will still be the same devoted loving person she has always known. That is what matters most.
