Sam M's "Get over him" is about the slow, uneven end of a breakup. Written in the second person, the speaker talks to "you" as if coaching herself through it. At first she seems to be making progress: the pain is fading, and the face she once loved is now just another one in the hallway. Old photos and his jersey no longer make her cry. Instead she sees him as a stereotypical football "douche."
Then the mood shifts. Looking at the stands where she used to cheer for him, she realizes he wanted her there, and the tears come back. She grieves for what she lost and the chances she let slip. The ending undercuts everything before it: she admits she will never truly be over him, because "he was different."
The tone is plain, raw, and conversational. The poem's honesty comes from that contradiction, since the speaker tries to convince herself she has moved on while her feelings say otherwise.
