Roommate Wants to Move Out but Hasn't Told Us

Hi guys! This year I and 3 other girls decided to live in an apartment together. We have lived here for over a month and everything has been going good as far as I can tell. Today I saw that one of my roommates commented on a post made by someone wanting to sublease their apartment and she said she was interested. She hasn’t mentioned anything about wanting to leave to us and has seemed fine. I am really terrible about asking and talking to people about this sort of thing and would love some advice as to how to bring it up and stuff. Thank you in advance for your help!

I would be direct and just ask if she’s unhappy and looking to move out. Then I would remind her of her obligation to continue the lease (hopefully her name is on the lease). If you don’t want to talk to her alone, get your other roommates together.

Whose name is on the lease? If hers is, then say “I noticed that you had commented on a post about wanting to sublease and apartment. I just want to remind you that your name is on the lease and that you are responsible for your $400 a month no matter what. May I ask if there is an issue that we could address?”

if her is not on the lease, then it could be “I noticed that you had commented on a post about wanting to sublease and apartment. May I ask if there is an issue that we could address. Otherwise let us know asap so we can start looking.”
