Even in that scenario, which is actually very common, it usually doesn’t change outcome much in my professional experience. Usually there are many other reasons they are not leaving and often they will say things like “you deserve more/better” “if you choose to leave, I would understand” . These are often ways to manipulate someone to stay longer as they are attempting to show they care and give hope in order for things to continue as they are.

I’ve seen many situations where kids are in college, roommate situation is still the same and person doesn’t leave.
