Someone has said the words most people long to hear: "I love you," "I miss you," "I want to see you." The speaker, though, can't accept them. The poem opens by quoting these phrases one by one, each on its own line, as if holding them up to examine them, and then comes the blunt admission: "I don't think I can believe you."
The reason follows in short, plain sentences. Too many promises have been broken, too many lies told. The repetition of "too many" makes the hurt feel built up over time rather than caused by one moment. The last two lines are the saddest. The speaker has lost trust and hope in people in general, and the closing "Even for you" suggests this person is someone they wish they could make an exception for, but can't.
The mood is guarded and tired, with sadness underneath. There's no anger or shouting, just a quiet, honest refusal to be hurt again.
