MY mother has been writing her own obit for years...that's funny-but not. She must fear terribly that no one will have anything good to say. True, it will be challenging to focus on the flattering parts, but we would not assasinate her in an obit, certainly.
Which, in a roundabout way, brings me to the subject of Love & Boundaries.
I think often about the ways in which I love my mother and the ways in which I don't - cannot.
I love my mother in a distant sort of way, never too close. Experience taught me to keep enough distance to stay safe, both emotionally and, to a lesser degree, physically.
Ironically, we are both terribly disappointed that we are not close. For me, the disappointment does not outweigh the risks, and for her part, she cannot/will not see why we are not close.
Basically, we both mourn because our fantasy parent-child love does not exist.
All that said, it is better in some ways than it used to be.
What apparently caused her to at least practice some self-monitoring was very much like what you describe above - a threat, simply put.
After a lifetime of constant criticism (causing me to doubt my every move), I had a child of my own. As far as I, the pediatrician, my friend with the PhD in developmental psych, and everyone else could see, she was a very bright child, happy, curious, engaged, 95 th perfcentil weight and height, developmentally ahead of of peers...no harm/no foul, right? Pretty good job with a pretty good kid, right? Not in my mother's eyes...
"You hold her too much..."
"She doesn't get enough sleep."
"She's always's sick (H got a cold once or twice)."
"Are you sure she should eat that? Drink that?"
"She's underdressed/overdressed..."
"I'm worried because you don't do this, that and the other thing...and you do this that and the other thing...."
On and on and on...This would be funny in a movie, but it hurts and it sucks in life.
Finally, one day (this time she called to give me the number of some quack doctor to find out what was "wrong" with H - what a movie, indeed), I said:
"Listen. I'm tired of this. The evidence is right before your eyes.The kid is happy, healthy an FINE. I work hard at being a Mom. I know I do a good job and I don't care what you think. You have never said one single meaningfully complimentary thing to me in my life, and I'm sick to death of it. As a matter of fact, from now on, if even one criticism passes your lips, I'm hanging up. Period. If that means we don't ever speak again, so be it. I certainly will not miss this crap."
For the first time in memory, she was silenced. After a minute she said, "O.K.". We then changed the subject.
Now, I can't say she's never been critical again, nor can I say that haven't let any of it slide (I have, in favor of the general peace), but it is much less frequent now...and she's even tried being complimentary (truly, without a "but" or an "if" attached) a few times, if somewhat awkwardly.
It ain't perfect, but it is better, and I thank the Boundaries for that.
You did absolutely the right thing, but you know that already.
