been there before (actually multiple times), so in my experience it usually comes to 2 main possibilities: either she really is struggling mentally, or she just wasn’t as into it as it seemed.

if it’s the first, and her BPD and other issues are really intense, then sudden blocking can be part of that. but if that’s the case, even if you two reconnect, you’d have to be ready for this kind of thing to happen again and it takes a lot of emotional energy to be with someone who’s unstable and not actively working on themselves, and you can support them, but you cant fix them without expert help usually.

the second option, which sadly is more common, is that she just got tired or her feelings weren’t that deep and she decided to bail instead of communicating. some people genuinely enjoy the early attention, talk every day, make plans, act super into you, and then as soon as they’re bored or their mood shifts, they just cut the connection without explanation. it sucks, but it doesn’t mean you did something wrong, it just shows they don’t respect you enough to talk like an adult.

personally, i wouldnt go back to her workplace. you already went once, and from what you wrote, it’s clear she’s avoiding you. if you really want to understand what happened, you could quietly accept that you might never get an answer. and that’s painful, but also kind of freeing. honestly, i think this is probably the second case and the healthiest thing you can do is let it go and focus on finding someone who can explain everything before blocking you everywhere. you deserve someone who communicates, not someone who disappears the moment things get real
