A lot of this narrative sounds like my life. In my case my wife knew of my gender issues from about day 1. She also knew of my utter failed transition experiments and I finally settling on being "Just a CD". The monthly or so escapes from maleness helped, but in time the shame and guilt of stealing what little time we had together on weekends, the effect on her of seeing Joanne whenever she looked at me for days afterwards, and the easy stuffing excuse of having a thousand other "More Important" things to do mostly put and end to that.
Until the excrement hit the air handler once again. After having too much quality time alone I came to realize I needed to take the Trans-Beast on for real. Found a super support group, started working on myself, and also started HRT and therapy. I grew a lot as a person.
I also grew in other ways my wife is not all that thrilled about. She is supportive, to a point, of what I need to do. Becoming a far better person then that lifeless, soulless "Thing" I was also helped with her. After 8 years of juggling I still manage to live, work, and present primarily as a male. A few years back I had the luxury of being able to life part-time as female. Those days are gone. Perhaps forever. Which makes it easy for my wife to readily say she would likely be able to handle me going back to part-time after a move from our "Village" filled with pitch fork and torch carrying neighbors. Full-time is definitely out of the question for her.
As my wife, therapist, and very very occasionally myself, will tell me "No one can predict the future, much less control it" TBH-I have an awful track record when it comes to predicting the future about myself, or personal things. Most days I don't feel like I NEED to transition. Yes, I have found joy in being out in the real world as the real me. I miss that I cannot at this point in life due to other priorities.
I do what I can to keep all aspects of my life in balance as best as I can. As you know, it is not easy with so many conflicting needs and wants. Most days I don't feel I need to fully transition. TBH - I have made a major transition, from a "Thing" and into a Person. A person who can now say I don't hate living in my own skin. A person who most days sees Joanne in the mirror and not "The Sad Old Man". That's "most days". Then, there are the other days

Far fewer and much further apart then what they were 8 years ago.
Transition is never inevitable. The sad suicide statistics prove that. Even for those that feel that they NEED to. Hopefully, if the day comes that I need to, I will be able to harness the strength I have gained and really have the confidence to carry through with transition because I really do feel I need to. Perhaps even if I simply want to, because the potential to feel and hopefully be 100% genuine far outweighs the risk it carries today.
