I had a 36-year-old BF who was a software developer with Microsoft in Redmond, when I was 48. He lived alone in a big new house south of Seattle. But he told me his family didn't accept his being gay, always pressuring him to change, especially his mother.
He started behaving erratically, and then seeing me less (we used to camp & motorcycle together, among other things). Then one day he emailed me he had sold his house and all his possessions (RV, motorcycle, grand piano, home gym, furniture, everything but some clothes), quit Microsoft and was going to California to live in a reparative community to become straight. I rode down to his house and it was indeed vacant.
How much of this his family arranged I don't know, but evidently he'd been planning it for a while, not something you can easily do overnight. Unless, of course, his family did most of it for him. Maybe they owned a lot of his stuff, I had always assumed he did, perhaps that was part of their leverage over him.
He emailed me again from California, said they had him writing software for them to pay for his expenses. I don't recall him saying whether they were a religious group. Anytime he went outside the compound he was accompanied by a chaperone, and they monitored his email. He wasn't supposed to have any contact with his "old life" and certainly nothing gay.
But with his software knowledge he could get around their restrictions, at least for the time being. Knowing our email might be intercepted I was very cautious in my replies, not asking if he thought he made the right decision, not advising him to flee, not compromising him, nor did he describe his private feelings about the situation. His emails were more like vacation postcards in contents. And then all email abruptly stopped without explanation, his account was closed. I haven't heard from him in the 16 years since.
Demonstrating that it's not only minor children & teens who go to these reparative places for "treatment". But even much older adults, who appear to be independent and self-supporting.
The sense of guilt over being gay is a very strong motivating factor for some people, a way to manipulate them. My former BF is a case I keep in mind when others preach to me that things like Gay Pride aren't needed, anachronisms at best. Whereas I think lots of us still need to have pride, even today, and experience broad community acceptance & support, or things like this will happen.
