What are the signs that show a guy hates a girl?

[Anonymous]

My friend used to chat with this guy online but one day it just stopped. Then when she met him in person he doesn't make eye contact with her nor like her posts but sometimes view her stories. Does mean that he hates her? I don't know much about guys so I can't tell if he hates her

Hate is a strong word but i think he lost attraction

He probably is not angry, just disappointment or mad at the time

He's rude to her. It's usually obvious, right?
