Thanks for all your input, everyone! My husband found the right description for my parents -- it's good to finally have a name for it:
http://en.wikipedia.org/wiki/Narcissistic_parentsThe situation I'm in now is that I have worked, intensely, consistently, and mostly successfully, on expunging their negative influence from my psyche. I had actually worked it out where I could see them from time to time and it was fine, even somewhat pleasant at times, in a very limited way. I even found a way not to let it affect me for hours or days afterwards, not letting contact with them reconstitute all the negative structures that were built up from a lifetime of neglect and objectification. I've managed to be more detached and compassionate, and afterward get mad and vent or just be amused instead of letting it trigger me into reliving old patterns. I also identified the child part of me still pathetically trying to get some kind of parenting out of them, and got her to accept that it wasn't going to happen, I am 40 years old now, and adjusted into relating to them as fellow adults. Notice me twisting myself into pretzels to try to make a relationship with them, and they....stopped pressuring me to come to every family gathering because they know that I am easily willing to not be present at all if pushed. THAT'S IT!! That's the sum total of concern they have shown or changes they have made in response to my many years of speaking with them, pleading with them, and attempting to work with them on it.
This latest desire to break with them was sparked because recently my mother did something that triggered me worse than I have been triggered in years (on New Year's Day, thanks Mom!), and frankly, I've worked too hard to climb out of the quicksand I received from them as my foundation for life to let some external sense of obligation drag me back down into it. I shouldn't always have to be the one to change myself to avoid being hurt by someone who was supposed to love me and is not supposed to do hurtful things to me. I just shouldn't have to do this anymore.
This lifetime has had strong slavery themes for me - I can name at least 3 slave past lives that came up for me spontaneously in my 20's, without being channeled (though some have been confirmed by channelings). I have spent most of my life fighting intense self-hatred and shame, the belief that I was invisible (and I mean literally - I was so ignored that I grew to believe that when I spoke, no one could hear me), that I did not deserve to feel pleasure or enjoyment, and that I only existed for the pleasure and service of others (you can imagine the winners I attracted with that belief!). I lived through the horrible results of that, and then I lived through some very painful and grueling years working myself out of that mistaken belief and replacing it with something more healthy. Right now, I feel like yet again working my ass off to have some kind of relationship with the people who were the source of that debilitating and killing feeling (AND DO NOT CARE THAT THEY WERE/ARE and do not feel bothered to do anything that is responsive to my feelings instead of their own) is just another form of slavery.
Maybe I picked my parents this life with the intention of breaking off with them and experiencing everything that goes with that - why not? I can tell you this much - when I imagine not seeing them or having them in my life anymore, I feel nothing but a sense of peace, relief, joy, and - finally - security. I feel sorry for them personally, but I'm not the sacrificial lamb for them.
Anyway, on decording -- I don't see it as some kind of cure-all, but I do see it as a way to help get any of their energetic remnants out of my space, should they attempt to contact me that way. I know my (abusive and mentally ill) sister tries to get to me through my dreams, which is also something I'd like to stop.
Well, thanks for listening everyone...I know I spewed a lot of stuff, not all of which is relevant and some of which could be kind of triggery for people who also have family issues. So I appreciate your forbearance and your kind, non-judgmental input. ?
