Hi ,
I have no 'words of wisdom ' , but I could tell you my opinion , and that is to go for it , do what you feel .
If your wife doesn't understand you ,it is her fault . After all , what would she say is you would ask her to live forever as a man ?
Maybe you could live in denial , and sometime you won't feel the dysphoria , but there will be times when you will regret that . I regret it now that I didn't followed the first signs , as soft as they was , and I lived some years in a meaningless life .
About loosing stuff , it is difficult . You don't have to really loose your daughter , depending on how old is she , sooner or later she will understand what you are going thru . About house , I don't know what to say , it is a big deal , I am not married so I can't say what chances you have or what should you do in this matter.
I am about to loose (although never really have it in the true meaning) my family : my parents , brother and maybe other relatives.
Anyway , my opinion is that you should go for it , and if your wife seems to become supportive , you could make a plan that suits the entire family . I mean for example delaying a bit some surgeries that are not paid by insurance , or something like that . But you should really live your life as you feel .
