Dear Ann Landers,
am a 20-year-old college student living with three other roommates the same age. One of our roommates, "Gloria," is causing a lot of problems for the rest of us. She is dating a married man. This isn't the first time she has been involved in an inappropriate relationship, but I didn't know about her entanglements until after we moved in together. The man Gloria is dating now is a lot older and has kids in their late 20s. He doesn't hide his cheating. In fact, he wants us to invite him over to "hang out." Gloria bragged about their sexual relationship, and his wife found out about it. She has been calling our house to see whether her husband is here. Now, Gloria demands that we not answer the phone or, if we do, that we lie to the man's wife. We have lost all respect for Gloria and would like to kick her out, but none of us has the guts. I feel horrible for this man's family and do not want to be caught in a confrontation with his wife. Please give us some suggestions on how to handle this situation.

Dear Oregon,
Give Gloria notice -- either she stops seeing that married man or she will have to move out at the end of the month. Be firm about it. Let her know that if she doesn't break off the relationship, you are packing her bags and she'll find them on the front porch -- and keep your word.
