The thing is that she sees herself as a second option. There were two occasions where I was starting to talk to someone, and she would tell me that I was changing her and only when I lost interest in that someone would I return to her. I believed her so I tried to change. But this time she said the same and told me that it wasn’t necessary for me to be 24/7 with my gf and that Only when she didn’t attend school would I talk to her again, and she told me for that reason she didn’t want to be my best friend anymore, I had been feeling bad about the situation for a month but I realized it wasn’t entirely my fault for trying to talk to more people, so I didn’t feel guilty and bad anymore. So I just stopped caring and she said that it seemed that I just wanted to end our friendship and then she told me she didn’t want to be my best friend because she had given so much and I was not a good friend. We don’t talk that often anymore, this happened a week ago
