Hey... I want to specify that during the relationship she was great. She is diagnosed aware and treated as far as I know, during the relationship I was the problem but I never expected her to move on in just 2 weeks with a guy I introduced her to. I'm no saint and I understand why she left me, but I can't understand and accept her moving on already. Sadly I made the mistake of spying on her today and I saw she put up a status reading "I sought and longed for something I could not quite name. But in you, I found it". It's hard to swallow, I can't take it. I was supposed to go to the gym today and now I just want to rot in bed. It feels like she loves this guy more already than she loved me in 9 years. At this point I'm not even sure if it was the BPD making her move on so quickly or if I've hurt her so badly during our relationship she genuinely just stopped loving me right there and then. I can't make sense of it all.
For someone with BPD, they always have a favorite person or a few favorites at any given time. That's why your relationship was great, she was all-in. But at the same time, their minds create unhealthy fears that the relationship is falling apart, that you're going to leave her, etc. So they stop being all-in and start looking for reasons to get out of the relationship.
With your friend, she saw potential and he quickly became her new favorite...that's so incredibly common in BPD relationships. And maybe for today, it is perfect for her. That will change over time though because that's what always happens in BPD relationships. The same cycle you went through with her, your friend will experience as well. And so will the next person, and the next person....
Why am I sharing this? You probably did things wrong, like you said. We all do at times. Relationships are about love and forgiveness, but BPDs struggle with doing that because of the pattern I described above. At first their partner is perfect and can do no wrong. But over time, they're horrible and can do no right. Both are extreme viewpoints that likely aren't true. That's the mental illness part of all this.
I tried therapy at first and it didn't really work, but that was before finding out she had in fact moved on already... Maybe I should give it another shot. I feel like I'm annoying everyone around me, my mother, my friends, I'm just gloomy and doomy. She's come back so many times during the years but it feels final this time, she really seems head over heels for this guy and it's killing me, truly.
I'm so sorry you're suffering, You mentioned in another post that you were supposed to go to the gym- get up and go! The way through this is to live your life and stay busy; sitting around only makes things 10x harder. And it probably is a good idea to take a few more therapy sessions just to talk this out and process it.
Wishing you luck my friend- please keep us updated.



. If she had moved on with someone completely unrelated I wouldn't have been as hurt and I definitely wouldn't have cared as much. It would have still hurt but way less than this. And to answer your question, if the roles were reversed, YES. I would 100% feel like I cheated. Not only this is someone I introduced her to, this is someone I was jealous of, someone I didn't like (and she knew the whys) and someone who always felt inferior to me for no reason at all. Also someone she very clearly got closer and closer until I said enough. This guy is genuinely soulless and fake, he is a super fake person I'm not sure how and why she'd fall for him. I warned her, too. Still fell for him.
