The pattern you describe is pretty much spot on in relation to my experience with my ex. the idealization at the beginning was very intense. constant re-affirmations of what a great person I am, how good looking I am, how intelligent I am, what a great husband/father I would make etc. The constant idealisation made me see things In myself in a new light, a way I've never seen myself.
The devaluing stage caused these paper thin walls to come crashing down - how can someone who said such amazing things then disappear without a whimper?
For whatever it's worth there a lot of stories here (myself included) that can relate

do BPD's tend to pray on those with low self esteem? do you think this is more of a subconscious attraction rather than a conscious one?

Hi Dave,
I think the answer is that as much as we'd like to understand it in terms of A or B choices (a choice of conscious or unconscious), the reality is more likely in the middle, the murky grey area where people can be partially aware of what they are doing, but at the same time driven by emotions/thoughts that they are less aware of, or aware of having to some degree, but not why (if asking why even enters into the thought process).
Likewise when you/I/others entered into this type of relationship, we may be aware that we felt drawn to this other person for various reasons, but maybe not so aware of that there are/were aspects of our own personalities, in particular our fundamental sense of self-esteem, that was/is far more fragile than we realized.
All that written there do seem to be key differences in how most people think/feel about themselves and others, versus how someone who has a disordered personality perceives self/others. It's these differences that are hard to comprehend, and that goes both ways to some degree. If you believe she has a borderline personality, it might help you to understand the disorder up to a point. Beyond a certain point though you probably can't understand it, plus your understanding it won't make her better, and worst case it can become an obsession that leaves you feeling worse.
To a degree it can be helpful to understand a disordered significant other (assuming she does have a disordered personality), even if the only thing you are able to walk away with is understanding that if she does have a borderline personality, odds are nothing you'd have done would have changed the long term outcome. You might find some solace in accepting that she ran from the relationship due to her own issues.
Unfortunately that is a double edged sword and hard to accept. Hard to accept because the flip side of that coin is that it's because of her issues that she so quickly idealizes (and devalues), and that also means (and I've been there myself), that as good as it felt to be idealized, it's also our own want to be idealized that is a big part of why it all happened in the first place.
I really would talk to someone about what happened though, whether that is here on the forum or with a friend/family who has been something similar, or a therapist. Talking about it helps most of us. I know it's also hard to believe, but long term? You really may be surprised that at some point you'll feel better about yourself then you have before. It's a difficult lesson, but what happened to you is also a potential learning experience. A chance to really learn about yourself, and ultimately to face aspects of your own self-esteem that you might have not been aware of, and then really feel good about yourself in a whole new way.
Best wishes,
