Ok, no evidence in what sense? As in she seems calm and normal or the flat isn’t trashed in the background? There’s two possibilities- one is that she did trash it, but in her shame and embarrassment she quickly cleaned it up (trashed doesn’t necessarily mean broken and absolutely destroyed, she could mean trashed like throwing tables and kicking things and punching walls and throwing things that don’t break but her use of the word trashed in her mind reflecting how much of a rage she was in- it felt like she trashed it. If that makes sense) then quickly calmed down (another thing with the borderline rage; you see the mess, it was cathartic, but then shame sets in and you clean it quickly and after this all can appear normal including her and her mood). Or she could have thrown a few things and exaggerated it. Or she could have remembered it different to reality. However the reality vs memory vs skewed feelings usually only presents when in, or still in the rage or emotional stage. For example if I’m still in a rage or high emotional state I will remember things different and they are exaggerated in my head. But when I have come out of it, and calm, I see reality, so if she has come out of it enough to FaceTime and appear normal in the chat, and no evidence of the “trashing”, I wouldn’t link this to anything I can relate to having borderline. Unless like I said she did trash it but calmed down, cleaned it, nothing was irreparably broken or damaged, and came out of the mood quickly all fast enough to appear normal within an hour. These moods do appear and disappear head spinningly fast so it’s possible. But it seems unlikely. Especially calling someone and appearing emotionally normal; if I have had an emotional episode where I have trashed things in a rage, it often takes me days to get remotely emotionally level again. During this stage I’m usually in bed, self comforting and having a lot of space, help from my fiancé (cups of tea and whatnot and thank god for him!) and during this recovery period, I don’t even look at my phone - messages/ social media etc, as I cannot in any way, interact with anyone. I just go into myself for days until I feel back to normal in myself. I can’t picture myself ever having an episode and destroying things then calling someone all within an hour. Ever. I ignore all messages if I even feel able to check and read them.
As to her remembering things you didn’t say etc, and this is all my experience, it is possible but unlikely. Borderline doesn’t change your perception of reality unless you’re actually in the high emotional state at the time. Then you’ll warp things in your mind - but if having a normal conversation and things come up that didn’t happen, doesn’t seem like a borderline thing. Although it’s possible that if those things she claimed you said happened during an episode, her memory of it will be skewed because in her mind at the time, being not so in touch with reality, she will perceive things incorrectly, and if it isn’t corrected at the time for example after she calmed down you didn’t talk and clear the air and remind her you didn’t say those things, it’s possible she remembers them wrong; as her borderline episode did when having high emotional states. If that makes sense! I have to admit that I have had times where I remember things differently to my fiancé. This is usually when I have had an episode and we didn’t have the “calm talk” after to clear the air and get the reality back. When we do talk after and clear the air and he reminds me gently of the reality, we remember it the same. If this makes sense. It’s very difficult (and dangerous) for me to try to give opinions on whether I think she has borderline or not, and irresponsible. But I can answer any questions you want if it helps you understand her and your friendship better and I’m more than happy to help with this. But I can only do from my perspective as I have done above. She could have borderline, for sure I can recognise some things you said about her but my experience of it and what you describe aren’t really matching, perhaps because of the examples. I mean if we take two examples and go into detail I’ll be able to understand more. If you tell me how she seemed in the trashing flat incident and how it appeared to be untrue (why do you think there is no evidence? Did she seem normal and happy? Could you see much of the background and the room seemed pristine? Was her trashing in another room perhaps? Did she look how she normally looks- hair and make up nice etc? Did she seem at all emotional?) and the remembering things you didn’t say or do- can you give one example? Like what she said you did or said, what context did she make that claim? The claim she made, in your memory of it, what actually happened and what was her version? Was she having an episode in your memory of it?
You don’t have to answer if you don’t want to.
I guess my point is without the details it’s hard to judge but her behaviour doesn’t match mine to a big extent. But every borderline is different too. Though I have read a lot about it and it doesn’t in my opinion match well. It’s also very complex. For example perhaps it isn’t resonating with me because her way of dealing with it is the manipulation side. I have this too and I have to battle to not do it, so she could be remembering things differently or making up trashing the flat for sympathy to manipulate you into giving her attention - not to be mean or cruel and probably not even realising it. But because she is terrified of losing you and so she exaggerated in order to keep you close and emotionally engaged. This thankfully isn’t something I do, though I can be very manipulative in other ways because of fear of losing someone (to my shame).
As you can see there are a lot of facets to it all, and I know my reply is not really clear in terms of answering your questions directly. But borderline does present very differently not only in different people, but also in different people and their different types of relationships too. So she could well have it but it not be presenting like mine. Or she could have a different disorder. If you want to private message with real detailed examples I’m more than happy to respond to each example. As those are quite open to interpretation. But I understand you don’t want to put your friends details and mental health all over the internet of course.
I hope she’s well at the moment, I hope you’re ok as it can be so damaging to be on the receiving end. Feel free to ask more or to private message if you feel it’s too personal to ask on here. I’m far from a professional but with years of this and much research, I will try to help. I hope this has been helpful in some way to you
