have posted on here before about my mother (under a different username) - please no advice to go NC with her, as that isn't going to happen.
I am an only child. My father died last year. My mother has a limited social circle based largely on people she works with or late friends of my father's. Being charitable, I think she is neurodiverse and/or is suffering the long-term effects of being neglected as a child herself (she had a pretty rubbish childhood) .
Growing up, she could be very negative, and was very critical of my father to me, which I struggle with resentment over. She can be extremely negative and unpleasant about people unnecessarily - e.g. she referred to a girl I went to university with, who was slightly on the plump side as a "lump". She uses complaining and criticism as a means of making conversation and of expressing complex emotions. She either does not notice the effect it has on me or cannot stop herself from doing it.
I get that everyone needs a vent from time to time, but this is low-level constant, and I find it really difficult to handle. The curious thing is that she cannot take anyone doing it in return to her - e.g. I once thought 'beat her at her own game' and after a very difficult visit from my mother in law tried to do it to her - and she literally said to me 'you shouldn't say that about your mother-in -law!' - another time I called her to tell her about how stressed I'd been after spending a hot summer's day in A and E with a toddler and she told me I needed to get over it.
She struggles to engage with or respond to certain social cues. It's kind of hard to explain. e.g. we were out with her one day with my toddler, and she was filming on her phone, and then he started a tantrum over something and she just carried on filming and I have to spell out to her while dealing with a screaming toddler "please stop doing this". I went abroad with her for a few days last year to see a sick relative and everytime I FaceTimed my family she'd be sitting next to me getting her face right in the camera and talking until I wanted to scream at her, just let me talk to my son and my partner for two fucking minutes, I'll invite you over to say hi, I just want to be able to chat myself.
We are going on holiday with her for two weeks (I KNOW) and I'm feeling extremely 'triggered' because yesterday she was moaning about how last year it was difficult to book one of the restaurants at the hotel - but we managed it! and this year we are staying at a different hotel in a different country!
I've spent years trying to let this wash over me, but I find myself getting snappish with her. What I really want to do is spell out to her that her complaining has had a terrible effect on me, and I'd rather that she didn't do it, but she is a frustrating combination of sufficiently obtuse that I can't just hope that she'll pick up on a non-engagement or a hint and full of rejection sensitivity dysphoria so any sort of blunt or direct comment is devastating to her.
