Hello! Please remember that my response is for information only, we are not establishing a therapeutic relationship.
It sounds like you are in a very difficult situation.
Can you please tell me your relationship with this woman?
You through out a number of diagnoses for this woman --Bipolar, PMS (or PMDD), Antisocial personality disorder, and Borderline Personality disorder. As difficult as she may be it's not too likely that she has all of these diangoses. ;) What I get from what you are saying is that she's causing a lot of difficulty in your life!
I'm wondering why you want to try to diagnose her. It's difficult without the proper training, and even Psycholgists won't diagnose someone unless they see them for an evaluation. Here on Just Answer, we Experts tend to give "possibilites," but never a firm diagnosis. Does that make sense?
You seem to not be available, so I am switching to Q & A mode and we can continue from there ---
No problem --OK, if she is Borderline, then it is likely that she can be charming to strangers, manipulative to get her way, and have a poor perception (and memory) for reality.
I assume that you have no personal dealings with her anymore and just have to get through this court case?
My best advice is for you to stay as calm and unemotional as possible, so you don't escalate anything. Stick with the "facts" as you know them. Maybe print some information from the internet and give it to your lawyer.
Does she try to contact you outside of the court setting at this point?
It is very sad, because underneath the disorder, she is a real person (that you got to see a bit of), but the disorder makes it really difficult to maintain a relationship. People with BPD fear rejection and abandonment, and then behave in ways that can drive people away.
You might want to check out this book: Stop Walking on Eggshells... just to get some more affirmation and understanding of what you experienced. The book might also help you to develop some compassion toward her as well.
Best wishes ---
It's hard to comprehend. This behavior is called "splitting," where a person or thing is viewed as "all good," or "all bad." People with BPD tend to put others onto a pedestal, and then at the slightest perception of rejection/abandonment, the person comes crashing downward.
Stress ---it can trigger episodes. Another characteristic of BPD is the instability/difficulty regulating emotions.
I am sorry for all that you have been through with her.
Don't forget my advice above --don't get emotional in front of her (you can do that later), just stay calm, give your lawyer all the information you have.
I hope that this has been helpful to you. If it has, please "Accept." Also, please feel free to put my name in the subject line if you want to interact with me in the future about this or another issue.
