Does she love me so much she can't cope with a reality where we're not together, in which case this is a touching but sad monument to her commitment to a love stronger than reason, or does she really want people to believe she's a merciless sociopath playing with people's emotions for her personal amusement, perhaps as a self-inflicted punishment due to guilt from failing to live up to her many promises? If the latter she should know I'd have forgiven her long ago if she'd only asked.
Somewhere in her mind is hidden the truth, but this is how I prefer to remember her. Maybe someday she'll come to terms with what happened between us and be able to remember herself this way as well.
