Straight Spouses of Transfolk

I don't think that's fair, because they're caught up in someone else's transformational event that they don't get to choose. That always sucks. Plus they have to decide whether to leave the relationship or stay in it, and that means examining their own orientation in ways that straight people usually haven't done -- rather abruptly, and while stressed in other ways. And one of the ways that can play out is giving up that straight privilege if they choose to stay, because they're going to wind up with a same-sex partner. The stress is real, and there's very little support for it, and the support I've seen is ... actually far closer to what you described, the Str8t Spice stuff for people who left a transitioning partner. Support for people who stick around? Not so much. And if you want to have a functional family come out of that roller-coaster ride, there needs to be support for the very different experiences that people are going through.
