<human>: Recently, my fiance  (20 m) and I (19f) moved into a new apartment with a mutual friend (20m) and somehow contracted scabies (don't know how). We've both been itchy af and have been to the doctor who confirmed that it was scabies for the both of us. Our room mate (20m) has not had symptoms of scabies bites appear yet but I have asked him to get treated as well and to treat his clothes and linen so that our apartment does not get reinfested after treatment.

My room mate refuses to buy the lotion needed to kill the mites on his skin (if there are any on him) and refuses to rewash and dry his linen and clothes. I'm scared that if he does not get treated the infestation of our apartment will not go away. I'm almost there to asking him to move out if he refuses treatment . He is not on the lease.

Condense the text into a few key points
