I am very nervous of her intentions, but I am just enjoying the pause in the mayhem. I think she realised that she'll have to get a job if she gets divorced. We had a discussion (fight) last week about her contribution being zero financially. I said she needs to get a job, she said "No", she is building a business, which unfortunately is a money drain not a money generator.
Don't assume that the change in her behavior is a deliberate one. Perhaps she has more motivation to be nice to you. But I would argue that her behavior is dictated more by her disorder than anything else. Before, she raged at you because that's what she needed to do at the time (because of her disorder). Now, she not raging at you, perhaps because she has someone else (besides you) to devalue. But there's a good chance that when she needs to rage again and you are an available target, she'll do it to you.
I have been consistent throughout the separation, saying I want to be friends and see what happens thereafter. I'm desperate to maintain a working relationship for the children's sake, at least. I thought she would rage at me forever, and this new "nice pill" she's taken caught me completely off guard. I'm not naïve enough to believe she's suddenly decided to be friends for the benefit of either me or the children.
I think when you need to maintain a functioning relationship with a person with BPD (pwBPD), emotional distance and formality are your best allies. Having chaperones present can also be a stabilizing factor -- or at least then you will have witnesses to their bad behavior (which they will later deny).
This is more a download than a question, but anyone out there had the sudden switch from medusa to kind friend after 14 lies that she has filed for divorce. I just count them now. LOL
One of the criteria for diagnosis borderline personality disorder is "Unstable, intense personal relationships, sometimes alternating between “all good,” idealization, and “all bad,” devaluation." Medusa = devaluation, kind friend = idealization.
