Hi Reincarnate93,
I don't understand how I did absolutely nothing to cause this and she broke my heart and the new boyfriend has been with her for double that time and it seems like she doesn't treat him that way, it seems like he'll never be split black and that it was my fault
There isn't an expiration date on people with BPD (pwBPD) that indicates how long you can be with them before their illness become apparent. But you are right that there is nothing you did to cause this; she had this illness before you ever met her. It might help to know that what may be the biggest trigger for her disorder is her sense of intimacy. She might *tell* you that she feels close to you. But as far as I understand this disorder, it's *only* when a pwBPD starts feeling intimate/familiar with someone that their fear of abandonment kicks in. It doesn't get more intimate than when you are having children together. And maybe it was that situation that riled up her disordered feelings and contributed to the miscarriage.
Maybe right now she is keeping her distance with the new boyfriend so that her disordered feelings don't overwhelm her the way it did with you and her more recent ex-boyfriend.
It "seems like he'll never be split black" but do you think she has been magically cured of her disorder? Do you doubt that she was ever sick? Because if she does have BPD, it is just a matter of time. And it doesn't matter to you because you are not in that relationship. Are you here to let go? Or are you here to make sure what's fair is fair? Because it isn't fair. None of it is fair.
while she was pregnant she stopped taking her anti depressant meds. could this be why she treated me this way?
Anti-depressant meds just make you less depressed. It doesn't cure personality disorders. It might lower the edge on feelings, so that couldn't have helped. But anti-depressants don't make you not have borderline personality disorder.
it seems like every time I even try to talk to her she just shuts me down and says "I don't wanna talk to you" I realize now that it was a mistake to even try to talk to her but I really wish I could just get over her. because she's caused me so much pain
You won't get over her by trying to talk to her. You need to figure out how to help yourself *deal* with the pain that has *nothing* to do with her. Look into how people get over being addicted to alcohol or drugs because you may need that kind of support.
and I also don't understand if she truly has BPD with which she was professionally diagnosed, how has she been with her new boyfriend so long? and why did she not treat him this way?
You can be "professionally diagnosed" with being an alcoholic and still choose not to change your behaviors. Same deal with BPD. She may have been diagnosed but may choose not to do anything about it.
Why don't you read about other people's experience here? Some people have stayed in relationships with pwBPD for years or decades. There is no magic timer as to how long it can last. It can last for 20 years... .20 god awful years... .but what do you care? This has nothing to do with you. And you won't get over her by spending your time thinking about it.
Best wishes,
Schwing
