You did the right thing too. I hope you've made some new friends since all that. I've cut off the one friend and had to distance myself from other friends that enabled him. You invited both of us to your birthday party? Guess I'm not going. The good news is that this has pushed me to value my friends that aren't crazy and make more deep connections with new people. I hope you were able to make the same shift.

Tangent: I swear the best way to break down the narratives around trans people is to just make casual friends with a trans person. You naturally want to respect your friends and see them as normal people and then all the talk about bathrooms, grooming, etc just seem so silly. Years ago I felt like the bathroom arguments held water. Then I watched my trans friend just walk into the bathroom and it seemed like such a non-issue after that. Now she's one of my best friends.
