Comment: Here's my take. As a mother trying to think how this scenario could come about. Why would I have my child give up their bed for what was expected to be 3 months? Probably to light a fire under my own kid's butt to move out. Given the little information we have, except that they live in Toronto, I will assume that LW is older than the cousin. Cousin is first time out of university and their own home, LW is a few years older, has a job but considers growing up and moving out "Too expensive". I don't think the mother is a doormat, I think she probably doesn't feel like she can criticize her niece's behavior when her own daughter seems like a miserable, immature person.
