A very well written and encouraging response, Kari. I like your point of view and approach.
Yes, it is scary to 'fess up' to your O&O. It's even more nerve wracking after the big sit down. Both my wife and I went through a period of doubt about the staying power of our marriage. She looked for assurance that I would treat her fairly in a split up, and I looked for anything in her words that hinted at acceptance and understanding.
I strongly agree, Kari, about assuring one's wife that transition is off the table. Even if it turns out not to be the case, it's too much to expect a wife to accept at this stage. I'm not suggesting lying to her. I'm sure most of us late hangers-on have no desire to turn our lives inside out either. As you say, Kari, it's important to let your spouse set the pace.
The one piece of advice that I want to put forward is the need to erase all the old stereotypes and come to an understanding of what being transgender really means. My wife has come to see that for over 30 years I was transgender and we were able to make a go of it. Why should her discovery of that fact now suddenly change the basis and the vitality of our marriage? Once that realization took hold, it opened the door to finally finding the freedom I needed to be myself while honoring and attending to my wife's needs. She will say that there are many things about the new real me that are so much better than the old fake me. This is the answer to the "what's in it for me?" side of the equation. Marriage is a give and receive contract that must be balanced for it to pass the test of time.
