My roommate doesn’t want me using scented things in my own room?
Sounds like you better start searching for a new roommate just incase things go to ****. ***ROOMMATE WANTED: MUST NOT BE ALLERGIC TO SCENTED CANDLES***
Tell her I will be using scented things in my own room. I will not use them in our common area. I suggest you get a room purifier for your room for your allergies. If she calls you names and gets out of hand. You seem to upset for a constructive conversation. Excuse me. And ignore her completely. Go make a meal. Go back to your room. Turn on TV. Leave the apartment. Do not Dante or argue with her, You may want to get a key lock for your bedroom door . Lock it when you are not home.
She sounds like a spoiled brat. I would rub some raw ground beef into the carpet under her bed and see how quickly she starts using scented things to get rid of the smell!
