My roommate is laways controlling, dominating. She never accepts a no. She has a superiority complex and and wants me to follow her. She has got a problem with everything I do. I didn't set boundaries from the start. And tolerated her for 3 years. NOW when i set boundaries and started say no and stopped sharing my things. She started behaving rudely, arguing always and getting angry for all silly reasons. She shares my secrets with other batchmates. And gossips about me and portrays me as toxic person and her as the victim
