I am going to chime in with the rest of these folks....you made a "boo boo" by asking about getting an AIDs test....IF...notice that is a BIG IF....sex/ML should come up make sure YOU have protection to use....THEN IF...another BIG IF....should things really work out then bring up getting a test so that you can eventually do away with protection then....that is how I handled it....at first he was put off but then realized that I was being SMART....and eventually down the road he got a full STD/HIV/AID panel done....
It sounds like for now you should just nicely co-exist as if she were just ANY other roommate!
