I read all these comments and I am sad. Relationships are challenging with Gender Dysphoria, and too many fail. We need to realise that gender incongruence is locked into our brains before we are born, it isn't something we choose, or something we can change. Conditions which conflict with our gender identity cause dysphoria, and this can get severe enough to destroy our health. So it is not wise to ignore dysphoria.
Anything you do to affirm your gender identity will reduce dysphoria, but it can be short lived. We don't have to dress or transition, merely thinking affirming thoughts can help. I have achieved relief by writing fiction stories, taking on typical female activities, or growing my nails out just a bit. Friends have used female avatars in gaming
But this is all just temporary relief, and doesn't solve the problem with spouses. Think about why they love you, and you might find it includes some characteristics from being trans. If she can learn that you were born this way, it is part of why she loves you, and that you want to work with her to find ways to keep you both together, and you healthy, she just might come around some.
I discussed these things with my wife, and she committed to stay with me and work with me to find solutions. We were partners in marriage and in all decisions related to trans. She saw that I tried my best to accommodate her dreams, and realised that transition was life saving for me. She drove me to hospital for my GRS, and cared for me after, but in the end, it was too much for her. We parted, but remained best friends. We both realise that I had to transition to get my dysphoria down to sustainable levels, and we both decided to do it. We had 30 great years, and both feel we did everything we could. All you can do is work with her to find a way forward, and know it may or may not work. I can tell you from experience, ignoring dysphoria eventually leads to disaster.
Hugs,
