I don't think it's a bad marriage. I just see two young people who love each other, are figuring things out, and are reacting to each other. The reactions on both sides are normal. Maybe if Lynn stops telling her wife that she's a woman, things might improve. It's hard to reach a middle of the road compromise when a spouse tells the other spouse they are not the gender they married, which implies eventual transition even if Lynn is adamant that she doesn't want this.
Lol. My SO in the beginning also told me that she had no plans to transition, and it took me about 3 years to believe her. Had we been married and had I been much younger, I might have tried to come up with rules too. :p
