At what point did you realize someone didn’t like you?

I had a friend. We’d been friends for 9 years when she suddenly said she hated me. It’s been a few months since then. I asked her why, but she didn’t even know. She said I suddenly seemed annoying, the way I look, my gaze, my voice, how I talk, my body language, everything about me felt disgusting to her.

I mean, I kinda understand her because I don’t like my voice either. Then I talked to my mom, she gave me a new perspective and helps me open my eyes that people change, and that’s okay. I’ve forgiven her. After a year, she suddenly wanted to be friends again, lol. I didn’t hold a grudge tho, so I accepted her back.

But I still want to know how to tell when people suddenly start disliking us, so I can mentally prepare. Ngl, this shit hurts a lot than you think ╮(￣▽￣)╭
