I want to believe she doesn'T know any better but I'm starting to think that might be wishful thinking - because of soo much gaslighting. If they thought their behaviour was ok - they wouldn't need to gaslight like this.
Please may I share that I think that is an excellent question. For me it is a question that needs to be asked to construct how I view my own uBPD mother - is she basically OK, just ill, or is she aware and therefore needs to be held responsible.
A Legal PerspectiveTo get a perspective, I looked at the legislation regarding child abuse - in the UK this was set down in the 1930s. My own mother's behaviours were technically illegal.
So did she have the excuse of illness to exonerate her illegal behaviours? Two measures might be used legally to decide:
1. Volition - she had the power over her own actions (this is easily proven since borderlines can turn it on and off according to time and person: my mother would never rant and rave at certain people!)
2. Ability to discriminate right and wrong - yes, of course she could, in fact, ironically, the borderline has an intensified black and white view of world.
So, legally she might have difficulty defending herself on the bases of mental illness! (Assuming she even knew she was borderline, which I presume she doesn't). In law she might be expected to be sufficiently self aware to regulate her own behaviours through a combination of volition and a sense of right from wrong.
Admission of Bad BehaviourMy mother has only once ever conceded to bad behaviour. Her first trip to visit me in Australia (I migrated from the Uk as a young adult) - on the first day I took her out to a seaside suburb (Manly-Sydney) and ranted and raved at the thought that she might not get an omelette for lunch when I said I wan't sure were the best cafes were in Manly for omelettes: oh what a backward country, why had I dragged all that way from the UK, blah , blah , blah (of course she ended up having very expensive Thai king prawns). The next day she said something about vaguely remembering being silly about an omelette. Hmmmm!
On her last trip she behaved so badly I wrote and told her she wasn't welcome in my house anymore and cited a long list of unacceptable behaviours. Her response was to totally avoid the issues cited and start carrying on about if she'd left me out of pocket just tell her how much money to make it right.
One time I challenged her because she was persistently foul towards a girlfriend (as she has been with every girl I've ever dated that I was stupid enough to let into her presence) and she sat and cried and didn't' say anything ("transfer from being the abuser to the victim: "oh look you've hurt me so badly you made me cry".
Always Somebody Else's FaultI just found out that my mother tells friends what an awful childhood she had. This just doesn't gel with the stories I heard from my Grandmother. In fact my mother was seemingly either born borderline or accrued such traits at an early age, being a a little madam of a child throughout: refusing to recognise her younger sister from birth, being at war with her father, and expressing some gender dysmorphia (insisting on a boy's name, getting Gran to make her trousers and hanging out with the local farmers).
So in her eye's she's not the problem, everyone else around her is: on the relationship casualty list of sister, father, husband, son and various bosses at work!
But she must realise she's not normal!
Recourse to MartyrdomSo the borderline lapses into martyrdom as a means to justify then impact of their bad behaviour. My mother still rants about the loss of father to divorce in 1968 as if the sense of martyrdom proves her depth of her (sick obsessional and dark) "love".
Gaslighting / Blame the Other PersonIt is very easy for a borderline to "groom" a child. Not just the emotional / psychological manipulation, but the fact the child knows no other parental role model and always seeks to please a parent.
I suspect my mother kept me away from medical examination when she suspected I had stress related symptoms (my first migraine was traumatic and I had no idea what was happening to me and she never rang for a doctor!).
Somehow the borderline finds a justification - their sick view of love (remembering that violations are usually done in the name of loving and caring).
I just don't accept that she is unaware (she knows she has a problem), or stupid (she is very manipulative).
She has blamed me for her not finding another partner, for not knowing what love is in my life, goodness knows even the spots on my face as a self conscious teenager were somehow ballooned into a profound character flaw and mentioned every breakfast time ("my, your spots are bad today - why don't you do something about them".
ConclusionIt is my opinion that my uBPD mother is actually quite aware of the impact of her behaviours. It's just that she's highly unlikely to admit such because that would mean admitting her whole life has been run as a train wreck of her own making.
To admit her behaviours now would mean having to accept she was an abusive parent, a "failed" wife, a "failed" daughter and a "nuisance employee" in the workplace.
This is just my own personal opinion - at the very least from a legal perspective she is culpable and I regard quite aware of "wrongness" of her behaviours and their likely impact.
I might add I have very little sympathy after being at the receiving end of decades of abusive behaviours: that I believe she is aware is a significant reason for not engaging in any meaningful level with the woman.
PS. I wouldn't be letting my mother anywhere near her grandchildren, were I to have children of my own: she is just too dangerous to be trusted on the emotional / psychological levels.
