I am pretty much in the same boat. I know, or really feel, there is no way in this lifetime I can transition. I got a good a 30+ years invested with a woman I love dearly. Though she knew of my gender issue from day one, I felt I was over it for teh most part. Just the ocasional cros-dressing was all i needed. I was able to deal with life serving me a few s^%$! sandwhiches during those years the last serving was a whopper.
Dealing with that led me to looking back back at my life and how I handled my trans issues. So I decided to figure out the trans stuff, the root cause of most of the crap in my life. Finding a TG group, seeing a therapist helped tons. Iwas lucky to once again be afforded the opportunity to life part-time as a femal. This time, after a lot of self help, fairly sucessfully.
All which ultimately made my life more miserable
I have a V-E-R-Y long list of have-to's and responsibilities I agreed to. I am honor bound as well as morally bound to live up to. Decisions I make do not only affect me. Twice in my 20's I experimented, twice I opted for "normal". THat was the understanding my wife and I entered a partnership under.
You would think her knowing and being sympathetic would make things easier. It doesn't. Every wife and family must deal with the same crap. In time I know many of the responsibilities I can discharge. Yet my wife's words alwas haunt me"Who in their right mind mind
wants to be a 56v y/o woman. In 5-10 more years the answer becomes even more absurd
