It sucks and it hurts, I hear that and I understand it. Your wife's apparent transphobia and intractability about this aside, what I'm not hearing from you though is acceptance of her needs and wishes. I expect she is heterosexual, and if so the bottom line is that she most likely does not want to be sexually intimate with a women let alone married to one. Just as we cannot expect or demand that a gay person change their sexual orientation, likewise we cannot expect the same of straight people. And while it seems reasonable to say "but we're the same person they've always loved", to them, physically at least we no longer are. Many straight women love their girlfriends dearly but they would never be sexual intimate with them and have no desire to be.
When it comes to relationships our transitions are a two way street, it's not all about our needs, it's also 50% about the needs of the partner. In your relationship's case - given her conservative outlook, her heterosexuality, her transphobia - then your transition is a bridge too far for her. You may want and need her to come along on your journey but she doesn't. It's heart crushingly painful I know, but the sooner you can understand and accept that and begin the process of healing and moving forward then the more at peace about it you will be.
