so this girl at school was my friend for a really long time, and then she just flat out stopped talking to me. she didn't read my texts or respond to literally anything. so i asked my friend if he knew anything about this and he said that she told him i was too negative and stuff like that. i told him it was my opinion if i didn't like something or whatever, and we carried on doing whatever the forget we were doing.
should i address her about it or just stop talking to her?
