Hi Underbristol,
It seems to me that for now, you might be trying to ":)etach" from your relationship with B. Unless she decides to try to reconcile with you (which is possible), at which point you will need to decide if you want to "recycle." But in all likelihood, she may just end up abandoning you again at a later time.
What is going on in her mind? Does B have any concept of my love or actions/behaviors for her?
I'll try to explain some of the behaviors you describe and relate them to the diagnostic criteria for borderline personality disorder (BPD) and hopefully some of this will be helpful to you.
For me, (and I honestly assume her too) fireworks and shooting stars were seen and it was truly "love" at first sight. She is beautiful woman with all kinds of beautiful personal traits and qualities. We started an affair. She made me feel more ALIVE than I had/have ever felt. She rained-down attention and acceptance, and love abound. We had so many connections intellectually, spiritually, and physically that life without one another just didn't seem possible.
... .she would "hook-up" with someone (5 others) and expect me to mindful and open with it, and I had one hook-up and she became unbelievably jealous. Also, during our relationship, she maintained an occasional sexual relationship with her husband.
People with BPD (pwBPD) can exhibit impulsive behaviors including spending, sex, substance abuse, reckless driving, binge eating, among others. My understanding is that they gravitate towards these impulsive behaviors as a way to soothe or avoid their disordered thoughts and feelings. I wonder if B uses her relationships with others as a way to avoid her disordered issues.
PwBPD can also exhibit "identity disturbances." Such that when they "idealize" someone (such as when B fell in love with you), they could also assume a variety of personality traits that would lead us to believe that we are so well suited for each other. My observation is that pwBPD often change their identity depending upon whom they are attached to at the moment.
I thought B was passionate, and full of life and desire. She would pressure me to hurry-up and leave my wife, and offered critique when I decided to do it through counseling - what I thought was the only healthy way to end a marriage, and a lengthier process than harshly "walking-out".
PwBPD can also perceive abandonment, and exhibit "frantic efforts" to avoid this abandonment (real or imagined). You might consider that whenever she felt particularly attached to you (such as during your most intimate moments), she subsequently *imagined* that you intend to abandon her. Perhaps this is why she pressured you to leave your wife; she imagined that you might choose your ex-wife over her and abandon her. Remember this is a disordered behavior; there was no action you could do to change these disordered feelings for her.
She began to list all kinds of ways that I had brought HER pain and suffering, all the while, completely ignoring that I was leaving a 15 year marriage, and destroying the life that I had known, my career networks, and my wife/partner's life - all so I could be with B.
You see, even though you left your wife, she *still* imagined that you intend to abandon her. This is the pain and suffering she describes. I suspect that she is unwilling to consider that she feels and thinks this way because of her disorder -- so long as she has willing participants, she can always blame her disordered feelings and thoughts on other people.
She so often talked about her fear of abandonment and then in every possible way, SHE ABANDONED ME.
If you accept that her fear of abandonment is disordered and that there is nothing you can do to mitigate her fear of abandonment (because it is due primarily to her disorder). Then you can see that it is only a matter of time before she may choose to abandon you; because the only way for her to *avoid* abandonment (which she imagines) is to abandon you first.
Has she villainized me? Is she really blind to her own actions?
This is the "devaluation" part to the "pattern of unstable and intense interpersonal relationships." She is blind to all else when she is overwhelmed by her own (disordered) emotional states. When her feelings are not so prevailing, then she will be able to function as you'd expect.
She has a fear of abandonment, abandons me, and then constructs evidence and proof that I abandoned her?
That's exactly right. Except you got the order wrong. (1) She has fear of (imagined) abandonment. (2) when she experiences sufficiently overwhelming (disordered) emotions, she will construct "evidence and proof" -- also know as feelings = fact. (3) then abandons you.
Will she ever talk/acknowledge me again?
Maybe. Only if she needs to idealize you more than she needs to devalue you.
Is her reality completely different than mine?
When it comes to interpersonal relationships, yes.
Best wishes,
Schwing
