The only "rule" that exists is visitors are a no-go if the roommate OBJECTS.

For all we know, this aggrieved individual wanted her roommate to read her mind.

Also, she'd been at the school for three years--she didn't have a single solitary friend other than the one suicidal roommate?

I think your comment about realizing her limitations was probably on the mark. Surely she could have gone round and had a chat with the potential roommate(s) before packing up her stuff? That's what people with a little maturity would do, regardless of their mental health issues. I don't think she tried very hard to actively participate in solving her problem.

I dunno--like I said, I have knowledge of Stonehill's accommodation expertise, and some requests are unreasonable.

I'm not on anyone's side here--if I were betting, though, I'd say the school isn't going to have to fork over much if anything.
