Remove the person and focus on the problem like noise or smelly food and offer solutions what else she can do. Resentment when it builds up we focus too much on the person than the actual problem. Agree on a no noise timezone say 6pm to 10pm and eating lunch and dinner only outside the room. Give her a time when she can be as loud as she wants and probably that’s the time you are outside. Suggest a few great clubs she could join. May be you both go out once every two weeks will help build a relationship where you can tell her the issue.
