What you want is not reflective of what your wife wants. Your wife is obviously not gay, she wants a man, not a man wanting to be a woman. No issues. You do you and let her do her. You can't expect the relationship to survive because of your need to transition. Your body is telling you what you want, her body is telling her what she wants. Neither align with each other, which is one founding part of any sexual relationship, ie. marriage. She never signed up to marry a woman, or a man wanting to be a woman, so you really can't expect anything but this reality from her.
Disbanding your relationship should not be your core focus, just get it out of the way and accept it, so you can focus on getting your self identity sorted and thus the rest of your life.
Didn't expect, I think I had hoped she would feel different, but here we are.

You Say "man wanting to be a woman"
I need to point out that this is not me.
I know people may find this difficult to understand, Some may get a choice to transition or not, however My dysphoria is so strong, this is not a choice for me.
Trust me I don't want this... it really is a confronting position to be in when you are in conflict with yourself to this extent.
I want my family, I want my son 100% of the time. But my urge/need to be pretty/woman is so strong & is winning and ultimately costing me my marriage/family. =(
