Irksome.

Potential roomie is refusing to budge on the cohabitation issue, unfortunately. Apparently. it's hardly fair for me to want a touch of privacy when she's gotten used to having him around. She says both we have to be willing to 'make sacrifices' and 'help each other out'; all I want is to not have a guy sleeping in my already cramped room.

Perhaps this is why her former roommate is moving, no? I may need to go to the housing office or something, see if I can't get another transfer. I don't want to force her hand on this until I run out of options, the last thing you want is a pissed off roommate with clear access to your toiletries and valuables.
