I can think of several possibilities, but I'll leave their plausibility for the reader to judge:
- She was also cowardly about how the relationship ended, and could never work up the nerve to confront him in person. In my own dorm doors were usually kept closed, so if you didn't seek someone out, you would rarely see them at all.
- She knocked on his door, and he ignored her then too, but omitted it from the article, focusing on where the relationship didn't go rather than exhaustively detailing how it ended
- The two people kept separate schedules that meant they often weren't home at the same time, save sleeping hours (or, if either had a flexible-schedule night shift job, as my own roommate did, not even then)
- The relationship occurred near the end of a semester, and both parties moved out about the time it ended. They no longer ran into each other.
