She’s leaving

She told me she wants a divorce but I don’t want one. She’s hard set on it but I truly still have hope she’ll come around. She’s stalled on signing a 30 day notice with the apartment and now she’s stalling to come pack up her things. Am I thinking too much into it? Is it wrong to have hope? She told me before she’ll think about it but then on Thursday she told me she wants a divorce and is set on it. Has anyone gone through this feeling of hope? Or do I let her go.
