What could be more fun than having a roommate? If you’re living with a perpetrator of offensive behavior, you can probably think of a hundred reasons why you’d rather be flying solo. Unfortunately, something as trivial as an acid comment about your latest romantic interest can eventually lead to the need for a cease-fire. But still, the benefits can outweigh the risks. Cohabitation can lessen the burden of financial responsibilities, enrich our social lives, provide emotional support, and even add a certain degree of physical safety. (If nothing else, you’ll have someone nearby when you feel the need to check under your bed at night.) Whether you’re already there or not, something can be learned from those who have prevailed, as well as those who have chosen to jump ship. Through their experiences, you will be able to identify the counterproductive things we do that sabotage what could otherwise be a very rewarding relationship.
