As long as you both have heart, love, and well-being for each others, it will triumph all in the end. Cultural and social expectations are extremely powerful and alienating, never underestimate the power of culture. My girlfriend has been through the same things as your s/o, but we accept each other, because we both have heart, love, and well-being for each other and we overlook the rest. Other people see that as odd for each other(I look like a really femmy guy/my girlfriend is a femmy gg), but we see heart for each other, but I get it, cultural/social expectations can be extremely powerful where you live, work, socialize, and call home, its the glue that holds communities and societies together. I don't transition because of my home/work situation too, so I get it.
Sorry if I want on a wrong tangent.
