i donno wat happened to u but just consider it clearly, apart from wat fanny said, i wanna add a pt that living with friends is more difficult than strangers. At least u don have to care about the relationships with stranger if they have done wat u don like, u can scold her, kick her... but u can't do so with fren and it's hard to talk about conflicts with fren
It maybe exacting at the beginning but as both of you stay together longer, conflicts will come with it especially in hk such a small place. It's possible that u may lose a friend bcoz of living together, and that's y i rejected my fren's offer to share room with her
hope things will go back to normal to u and u'll make a right decision
