The speaker is talking about staying in a situation, possibly a job, a school, or a relationship, that other people say is bad for them. The poem doesn't say which. Early on, the speaker admits they once enjoyed it and that the real problem was one person, a correction slipped in with "I meant the person." That small fix suggests the speaker is trying to be fair, and maybe protecting someone.
The hope that things would improve keeps them there, even as each day leaves them "depressed, / Upset, / Deflated, / And dull." The short, flat lines make that exhaustion easy to feel. The title also hints that staying is tied to pride, to not wanting to be someone who gives up.
The ending is unresolved. "Maybe it's for the best, / But then again, / Maybe it's not" leaves the speaker stuck between relief and doubt. The mood is weary, uncertain, and quietly sad.
