We've been friends since we were 11 but since 3-4 years I started to really dislike my best friend. She only talks about herself, she complains all the time about the silliest things, she's judgmental, etc... I feel like I'm her therapist not her friend. I feel trapped in this friendship. I tried to "break up" with her, but she just came back in my life. I don't know what to do anymore?
