I think this is a really interesting thread. I kind of have a foot in both camps.
My parents brought me up to be academically successful - I always understood why, they were both from solidly just getting by working class backgrounds and saw education as the way out. And it worked - I went to uni, had a professional job and have a nice house in a nice street which I know some people look at and think "she's so lucky". I know I'm reasonably clever and I am confident in a work context.
The flip side of this? Both my parents were emotionally damaged: my mum was knocked about by her father and left home at 16 to escape him. My dad was both a bright, inspirational man and an angry short tempered bully. He had affairs with other women during my teens. Home was always a very cold place with no overt displays of love (though I do believe they loved me). Never any friends round for either of my parents.
I went to uni knowing I would never go back. Whilst at uni I met exH. I consciously chose him because he was so different from my dad. Seemed gentle, fun, had lots of friends, wanted a good career but not obsessed by it.
Fast forward a few years and actually I had married my dad despite my best efforts. Away from uni he gradually became more and more EA, relentlessly critical especially around my looks and social skills, obsessed with money. I realise now that he liked my earning capacity, but not much else. His big need was to be the centre of attention and to be envied by everyone else and he felt short-changed.
After a few years of this I just withdrew, carried on working like a dog and had children so I literally never had a spare moment to myself to think.
Eventually it all fell apart, I had a bit of a breakdown, lost my job, found out he was a long-term cheater and got divorced. I'm happily single now and that will not be changing. I couldn't handle a stressful job now.
So overall conclusions? Yes, the choices I made put me where I am today. I made a bad choice of partner and that has affected my whole life (I'm in my fifties now). It was pure bad luck I met him at uni. If I had been older perhaps I would have been more discriminating.
However, looking back I can understand why I made the choice I did with the knowledge and experiences I had. I did the best I could at the time and I have to feel compassion for my younger self.
My biggest worry now is that my DC will go on to replicate the relationships they have seen.
