text: how should i tell my dorm roommate i am moving out.? the reason i am leaving is because of her being a rude, promiscuous person and i am tired of her  bringing her guys over at 2 in the morning. i got out of the room because she smokes. i leave tommorow and she does not know yet. i am not confrontational so tell me an easy way to let her know. you should tell her in person. it doesn't have to be confrontational. just say your personalities don't mix. tell her you don't like smoke (are you allergic to it?); you need your rest for class and her early morning (or late night) visitors disturb your sleep.  if you are afraid she will interrupt you, you can always write it in a letter.
