I ended my friendship of 12 years last night.
Why would you end your long frienship?
I don't need friends like them, who are always condescending to me, they don't actually count as a friend.
If whatever you're saying is true, you did the right thing by ending your friendship with them. They should not have treated you with disrespect.
The entire situation is fucked up, I'm the one who's always right, but I'm the bad person. It's true, though, I am mad that I grew apart from her, while she is still looking out for my interests, but I still feel independent from her.
It seems like you still have a lot of feelings about this friendship, but just know that it's okay to cut toxic people out of your life. You shouldn't feel bad about it.
