The speaker is dealing with the possible end of a relationship and blames themselves for it. They say they never "start off with the correct foot," and they mention a cough and a virus, which suggests that illness or the strange circumstances of the time put pressure on the two of them. They call themselves "a curse" for bringing ruin to a love.
The speaker admits they don't know exactly what caused the distance between them. All they know is that the other person's words and face leave them feeling like an "emotional disgrace." They ask only for honesty: if things are over, they want to be told. They also hope to be remembered kindly, as something sweet rather than bitter.
The final stanza turns toward acceptance. The speaker wonders whether the two were "birds of one feather," but decides not to beg. The mood is sad, humble and quietly resigned, with a little tenderness left over.
