Emma,
That's a very good blog and much of it reminds me of my own past experiences. I was content at first to wear underclothes under male clothes, and then later on to cross-dress more completely but with no make-up or wig. I hid it all from my wife. You've read my first blog regarding telling my wife, so I won't repeat it here, but I have taken a long while slowing down what I knew in my heart would happen and still has to happen, complete gender change, my wife has known that I have been Trans for 3 years now and in that time I have slowly increased my femininity, without coming out as a full-time Trans Woman, It was only on Decmeber 3rd last year that I came out in the full-time femme role, or as some would call it pre-op transexual.
I love my wife dearly and by taking my time it has allowed her to adjust to my becoming to all intents and purposes a woman.
So please take it slowly with your wife and don't let it dominate discussion and interaction with her. Softly softly catchee monkey.
My wife said to me the other day to not let my Trans thing become a disability, what she meant was that she still wanted me to do all the things that I used to do as Steve, but now as Eve.
Good luck with hugs, Eve
