Hello, Steez
I am very sorry about your situation. I know how painful this is as well as many people here. We never know when to keep hope, but most of us experience frequent breakups.
My story started just like yours, I met my gf and she soon called me "my soul mate" "love of my life", we were "destined to be together" we felt like we knew each other from always, we "read each other's minds... ." we felt like we have found someone from the same planet after living all our lives among strangers. It was very intense. And you'll read many stories like that here.
Just today, when I don't even know if we are together or not, she told me in a casual conversation "I don't know if there are two people worse for each other in the planet". Some minutes later she was praising how good I am, and how my parents should be proud of me. But this time she is breaking up with me because "I'm good" and she keeps hurting me again and again, so the praise doesn't mean she's taking me back, at all.
It gets very complicated and you need to learn a lot about BPD to understand where each thing comes from.
The diagnosis is a hard blow. Specially if she has been online wanting to learn about it and found so many haters that speak about the stigma of the illness. She could see herself as a monster right now, and then rebel against it. As in "all sane people are the enemy". It is very sad if she was much better before the diagnosis. Some therapist prefer not to tell it. Because the Stigma is huge, and it can overwhelm the person with shame. Shame and fear are the worst enemies of BPD. They turn to rage, and isolation, and worse.
Think about her as a wounded animal, she will bite if you try to help or heal her. So approach with care and patience. Keep the contact if you feel is what you want. And keep your expectations low. Just remind her you are there, and that this is not what you want. Let her know she is not abandoned, just that, and wait for her if you can. Don't presure, but let her know you miss her, and validate her feelings a lot. (
