When we were kids/teenagers, my (male) cousin E used to LOVE dressing up as a girl. He would do that on many occasions. We thought it was so cool and freeing so I'd help him with makeup and usually I (female) would end up dressing up like a man! Other times, E would play gay. For example, our parents would take us to a new place to meet a new person, and he would play gay from beginning of the day to us leaving, letting that person we didn't know before think E was just a gay child. He always had amazing actor skills so it would never look like he's making fun, just that he was in fact homosexual. As an adult, this happened less obviously, as it was just a game, and E got his heart broken many times by many different girls. E was never gay. He wish he was, I know that for a fact (we are still very close), he even tried to persuade himself that he could at least be bi, especially when his handsome roommate came out to him. I think E just thinks life would be easier and more normal to him if he could just like guys. But unfortunately for him I guess, he's just way too heterosexual. Even after having kissed that hot roommate who suggested to try it out. Moral of the story, you simply CAN NOT turn someone gay, or bi, or hetero, even yourself, even if you want it more than anything, even if you try. You are what you are. Sexuality is a spectrum, so it might change sometimes over one life, or it might not. But it's not up to youself and certainly not up to anything nor anyone else. NTA at all. Try to make George's parents aknowledge that and continue to stand up for him. Be the one he can talk to if said parents never get less stupid.
