Hmmm, I was in your shoes a long time ago, and just stuffed myself into a very small box. I didn't work of course, I ended up looking up at a failed relationship from the bottom of a bottle.
Gender dysphoria will not be ultimately denied, but you do have choices and you have outlined them with clarity. Have you considered low dose treatment to ease the discomfort, but make minimal physical changes while you as a family work out a course of action. I'm glad you have an appointment with a therapist, that will bring perspective to your choices. Your wife is a remarkable person. I hope that you appreciate her grace.
Not really an answer, but a caution to be deliberate, but to follow your heart.
Hugs,
Julie
