Being unhappy about who you are and wanting to change that is admirable. It can also be a long, difficult and oft times confusing challenge I found since I had no real idea what that 'Who" really was or is. After 6 years I am only now getting a good clue.
To me "Transition" is simply changing. Something I refused to do for almost 40 years. I stuffed myself into "The Box". Now I am breaking out of it. I never saw myself as fully transitioning as in full-time, HRT, even GRS. OK, not since my 20's I had. When I started this process 6 years ago I still didn't. I just knew my life wasn't working and much of it came down to how I was NOT handling being trans.
Now, If you are set in your thinking that HRT, full-time living, and GRS is the way you need to go then there is little hope for the relationship. Ultimately, only you can say what is right for you. I took baby steps. I only wanted to 'fix' my life, not change it. My TG support group, a few angels I met there, some therapy and HRT has helped to fix me. Yes, the box has changed. My wife is slowly getting used to the breasts. She is profoundly impressed by all the positive changes in my spirit and as a person that has been taking place. She is also slowly debating and seeing a possible future with me living, at least part or my life, as a woman. Something I never saw or thought about myself 6 years ago when I dropped the T-Bomb on her. If I told her then what is happening today, we would not be together.
