OK, she is old enough to look after herself, and has consistently failed to show you appropriate respect as an older sister who has kindly allowed her to stay with you. It is not your job to find an apartment for her ( what a cheeky thing for her to say to you !) I agree - tell her to leave and give a week's notice, and then change the locks, and give her her belongings by arrangement, at a time that suits you. YOu would not be a Bad Person for doing so - she is a Bad Person for driving you to it. Maybe when she hunts for her own place and then tries to maintain it, she will appreciate what you gave her.
