stoic83... . if she has BPD then her disengagement from you was far from healthy... . she employed splitting and dissociation... . that represents major underlying mental health issues... .
You, on the other hand... . were triggered... . acted poorly and out of character at times, and you have posted here taking responsibility for it... . that IS healthy, self analytical and constructive

Two questions... . firstly, why are you putting so much effort into a person who is behaving so destructively?... .
Secondly... . what are you getting out of this that is positive?... .
Hey newton, I have been through this many times... . i think having a mother with hf BPD has made me immune to a lot of the behaviors though my ex gf was lf BPD. My mom split me a lot and also push-pulled and abused my dad in front of me for my entire childhood.
I have been aware for quite some time that I am not getting anything positive out of this relationship. Unfortunately my parental dynamics were that my dad did nothing for himself, everything for my mom, and took it out on me So to some extent I just figured I was programmed to fill this role... and since I am not a hedonistic person in general, though I enjoy fine things... . it just fit for me. I guess?
I am seeing a T tomorrow. Im for sure codependent and have little self-esteem. School and work has always been relatively easy for me... . I think maybe that I get gratification from solving very difficult problems (or bang my head against the wall for trying to solve impossible ones). Right now I am working on a few innovations , most of them are software related.
Im both brained... . but I think my intuition has served me well... . courses where i bested others: Philosophy of Quantam Mechanics, Computability and Logic, Philosophy of Math... . these logic and philosophy of science courses... . so I have a different understanding of the world than most people right off the bat.
I think the BPD had an extremely overdeveloped right brain and tended to feel her way through life rather than think... . since i have this innate intuitive ability maybe I felt like I met my match? She cant complete college... but she is eloquent and has a special intelligence to her from an overdeveloped right brain... . i could not lie to her... . she was like a human lie detector... but i am brutally honest anyways, so ME lying was never an issue.
I told her that we were both like X-men... .

. (She is rogue for sure... . poison) I tried to approach her from a common ground. I am an HSP (highly sensitive person) and pwBPD are very sensitive as well, but in a different way.
I can spot a BPD out in a crowd (well exaggeration) but I can tell when someone has BPD... . on the first meeting of them. The latest pwBPD i met, i knew in about 15 seconds of speaking with her. She was fully self-aware on medication and studying psychology... . she drank heavily and was a mess, but was intelligent and fun to hang out with and talk about BPD... . in the end i turned her down romantically and she split me black. (she was a model)... . she was buddys roommate when i was on break from ex-girlfriend and she told me that she thought my ex had more than just BPD.
I think I was trying to solve a problem from the past... . the most important problem of all. How to find the love that I never received from my family... . my ex was very familiar to me. But much lower functioning than anybody in my family. My sister tried to kill herself and has "i love myself" tatooed on her wrist... . she sounds BPD-ish. right?
I think they all might be narcissists and Im a co-narcissist. My BPD ex thought that she was a narcissist... . i am sure she had BPD... . but NPD too? Man i sure hope not... .
Either way... . i am worried i am a narcissist... . but T's tell me definitely not. Tell me mom's a narcissist. My dad is unremarkable... . was a shell of a man though he was a stock broker that made millions at one point. I think at the very least im a cerebral narcissist because my family never understood me... . Im hoping to reduce these tendencies. My first T said I have a lot of self doubt because my family never let me be right, even when I most definitely was... . it was like they denied my reality.
I have a problem with society at large... . but watching things like the presidential inaguration today gives me some hope.
I think that we our a society that is being controlled by fear... . and I think insanity is encouraged. I think it is fairly disgusting that people like to watch other people get hurt on tv and in the movies. I am removed enough from society where I can look at things objectively, and I have decided that it is hard to focus on the positives when the negatives are being shouted from the mountain tops... .
Good is boring in this day and age. Of course there are some great counter-cultural movements... . but I digress.
Being separated from all the other kids through school to some extent probably gave me some complex, and the BPDs idealization felt good... plus she didnt care that i was intelligent. That felt nice. I had to tell her flat out that I was smart( most people wouldn't assume I am smart... . many pseudos appear to be much more intelligent than me). After getting to know me a few times people would like me... . but put me on a pedestal, or they would just not like me... . dont understand my humor. I dont fit anyone's stereotype... im an outside the box kind of a guy. Zuckerberg is NPD for sure.
I haven't read a book in many years. I smoke a lot of weed to mellow out so I can spend time with my friends. I have been taught that being smart sucks and being rich and famous is cool. Ignorance is bliss, and if I had to do it over again I would definitely go back in time and make my mom take jello shots twice a week.
Hopefully my T can figure it out. People have told me to just go to grad school... . Im trying to get this software company off the ground... . i think i might be safer and happier in academia. I think if i make a lot of money, people will just try to take advantage of me... . so i self sabotage. I am very trusting and gullible... . my friends could always play tricks on me. Like taking candy from a baby. Embarrassing.
Maybe I just have no street smarts? I dont know man... . I get along well with a lot of different kinds of people, but maybe I need to find someone who is healthy... . not someone who has an overdeveloped right brain. I think if i could find a nice HSP who reads and has nice pillowy breasts and is less anxious than i am. I would be very happy in the relationship. Those are my three requirements for relationship during flea mode... . haha jk. I dream, i dream.
I like your posts newton. I think that your left-brained approach to this situation is what most of my IT friends take... . but that's where my system kind of short circuits?
Why do i put effort in to someone who behaves destructively?
Well there are times where I felt alone, and I wish there was someone who had my back. I treated her like I would want to be treated if i was in her shoes. This is called empathy.
I wasnt equipped to handle the feelings associated with her destructive behavior. I think since i learned to tolerate irrational behavior from my family as a child... . i think that it just felt comfortable enough to continue... . Getting bad attention is better than no attention... . right? My mom is a gifted writer, and extremely right brained... and gave my dad no love... and used to make my dad jealous by being nice to me in front of him, and he hated me and tried to destroy me in my adulthood twice.
(got me to quit my job and involved with FBI criminal putting my career in jeopardy, and breaking promises to help me when I made sacrifices that required he follow through with something leaving me in impossible situations and then screaming at me)
This cowboy is gonna be a lone ranger for a while... .
