Arnold has had two major crushes in the series; one on sixth-grader Ruth McDougal (through most of season 1) and one on a classmate named Lila Sawyer (from season 3-5). However, his most catalytic relationship is with his classmate and frenemy Helga Pataki.
Arnold initially rejects Lila's advances, but eventually develops a crush on her. But by that point, Lila has already gotten over her romantic feelings for Arnold and says that while she's flattered that he has a crush on her, she only likes him as a friend.
Ruth effectively left for unknown reasons after season 2, (most likely due to the fact that her main purpose on the show was that she was Arnold's crush, but since he got over her that ended her role) but makes appearances every now and then like being shown in awe at Arnold's geek party in "Cool Party".
