The Time I was Bullied by my friend

My friend was getting jealous of me because i was hanging out with someone else. Then she started spreading rumors about me and my new friend didn’t like me anymore. When I heard the rumor i was so upset and i tried to tell everyone it was fake but no one believed me. My friend thought it was funny and that it was ok to spread rumors and cyber bully. What do you think that my friend should of done instead of spreading rumors about me.
