Phoenix,
Here's one suggestion for resources. On the main page of the SSN there's a link for resources, and for trans, there's a reference to a book by Jennifer Finney Boylan, a trans woman, which is a memoir about her transition--it's not a book that supports straight spouses at all. If you want a book that is from the spouse's point of view, Christine Benevenuto's memoir of her husband's transition, "Sex Changes," should be there instead or at least in addition to Boylan's. Benevenuto divorced her husband. Helen Boyd's two memoirs (she's a spouse) "My Husband Betty" and "She's Not the Man I Married" are from the perspective of a wife who stays.
