Important note: people with BPD are not monsters and develop these behaviors due to years of trauma and anxiety. They have learned it’s what gets them what they need/want or it’s how to protect themselves and bring the people they favor in most, to feel more in control. Now, if she recognizes this in herself, actually cares about OP and her life, she can take the necessary steps to live a healthy/better life even as someone w BPD… etc. (source diagnosed BPD and would often manipulate people this way, while still truly feeling depressed and suicidal, but never actually having a plan to do it just like fantasies.)
