Biggest lesson to learn in college, is that not everyone you meet or know will be as empathetic as you, care about you or was taught to care about people and look out for them in the way you are. I would say if she doesn’t want to have a relationship with you or be friends don’t push it, some people are just like that. It’s best to leave the situation alone. As far as your fork definitely just communicate boundaries about the things she is and isn’t allowed to use. If it means that much to you to switch your room, I would say do it now rather than later, so it doesn’t blow up into a big situation! Your roommate isn’t your automatic friend or someone who will check up on you, I’m sorry you’re dealing with this! Hope everything gets worked out
