I think that in this song, she doesn't like someone or decides they aren't good enough for her, but she doesn't want to hurt them. This explains why she's "feeling so guilty", "holding my breath", and "worried about everyone but me". She has this extreme guilt for not loving them any more and wishes she still did. "Try to convince me".
She wants to not have to tell him that she wants to end it and doesn't feel the same way, because she is so scared of hurting him. She hopes he already knows, making her job easier, so she's prompting him with "won't you read my mind, "haven't you seen me sleepwalking". She is trying to get him to admit that they should end it so she doesn't feel so horrible, or feel like she's breaking his heart.
