It's really hard to come up with an answer to your questions because we don't know your wife, who she is and how she deals with things.
I have been going through the various stages of dealing with my wife in relation to my ->-bleeped-<- and the overall thing I can suggest is to give your wife time and space to consider what you are going through - no matter how much you want to charge ahead. Very tough, I know quite well, but time is what she probably needs the most.
The second thing that I would suggest is to offer her sources of information about ->-bleeped-<- such as websites, books, Wiki pages, etc. that can dispel some of the misconceptions that she might have about it. Don't push too hard, though, just make it available. Her being willing to look at that stuff might take months. It took my wife upwards of 6 or 7 months before she felt able to read the book, True Selves by Mildred Brown and Chloe Rounsley. (A book that I heartily recommend you buy for your own sake, if you haven't read it yet, as well as for hers.)
And lastly, I have always tried to be certain that the battles I chose were worthwhile - a sensitive judgement call that only you can make. The only thing that I refused to take was any hint of ridicule or any kind of dismissive attitude on her part. I had to make sure my wife knew this was a serious and important issue for me.
My wife accompanies me when I go to my therapist's (it's a long drive - good opportunity to talk). She had two or three sessions with him by herself and for the last two sessions we have gone in together. This has helped a great deal also.
The wives of transsexuals really get a raw deal, if you think about it honestly, from their point of view. For them to accept it means that they must accept the loss of their husband, the loss of their dreams and plans and, quite possibly, the loss of the esteem that their friends and family have for them, even if they don't stay with their spouse. The fears that they encounter from this are very real too. The transwoman gets her ultimate dream and the wife gets left behind. Try to remember that (yeah, I forget too) when you relate to her and it might make it easier to be patient.
