Pecator, you've really been able to step back and look at a lot here. Understanding BPD and BPD traits is a good way to try to make some sense of the r/s and the behaviors.
First of all, yes... . I have way to much information about my ex for being in N/C.
Yes. But that's OK. You recognize that it's not healthy for you. That's key.
It has to end.
Yes. I'm glad you see that and are ready to do so.
It seems like her values change as she mirrors her partner.
Yes.
She has changed her values (some deeply held values she expressed when we were together, like honesty and transparency) to fit her current r/s.
Yes.
It also keeps me from believing that our scenario was the healthiest. It certainly seems that way, but if she mirrors all of her partners, how can I say she was healthier with me?
There is no "healthier" for her unless she does serious work on herself. The most certain thing is that the scenario was
not the healthiest for you.
She was just mirroring me.
Yes.
More likely, she is just lost.
Yes.
She is a beautiful person caught up in a horrible disorder.
Yes. To a point. She still makes her own choices -- one of which is to choose not to work on herself. But yes, it is a difficult, horrible disorder to deal with, and it's heartbreaking when we fall in love with the "person" within, only to realize we can't hold on to that person.
Knowing has been helpful in that I can clearly see BPD traits. It has help me see that it is the disorder that I no longer want to be with, not her. I can grieve her and focus my anger at the disorder. I never wanted to walk away hating her like every one of her exes.
I'm very glad that being able to step back and look at her behaviors, both within the context of BPD and without, is helpful for you. It has been for me in my situation, too. You're doing what you need to do to process and heal.
You're under no obligation to hate her. I don't hate my exbf. I love a lot of things about him and feel a lot of empathy towards him. I have anger at his disorder(s), too.
But, like you are realizing, you can't have a r/s with a disordered person without also having a r/s with their disorder. It's a sad and painful truth, I know. But you are strong and will get through it.
Understanding and recognizing BPD traits in your ex can now help you start to better understand your own motivations, feelings, and reasons for needing that person and that r/s.
You are loving and empathetic. Turn that towards yourself.
