Mother - CP 6w5 (always been super unhealthy, unstable and codependent)
Father - 2w1 (always been super unhealthy and is probably a narcissist)
Eldest sister - 2w3 (she was the first grandchild and first child on my father's side and was majorly indulged and spoilt. One of the most manipulative people you can imagine)
Middle sister - 2w1 (very babied and super prideful. Major anger issues but she does a lot for my mother and her partner)
Me - 7w8 (completely neglected and only got attention when I performed/entertained. Everyone else's feelings went above mine, I was scapegoated by my family a lot and blamed for things unrelated to me. My eldest sister was quite the bully and manipulated the narrative a lot. My parents never stepped in or disciplined her for it. I am the only one who has gone to therapy, pushed myself to get an education, be deemed socially acceptable, attractive, funny, smart, accomplished, and liked. Very untrusting toward people and am often told I am intense. It is very hard for me to have self-compassion and to understand other people because I have been so gaslit and abused by my family. I had a long-term partner who was an SP 3w2 who helped me stabilise and focus, however, he was in an unhealthy enmeshed relationship with his 2w3 mother due to his 8w7 father neglecting their finances, my partner the youngest of three sons had to take on the financial and emotional responsibility of his mother. He is now in a relationship with a 2w1 who solidified his position in his social group which his mother pushed him into as it would help him social climb. His mother was always in his ear telling him what to do, saying that his eldest brother was manipulated away from the family by his wife when in reality he didn't want to be his mother's husband anymore as he had his own family to look after. She also manipulated my partner into thinking that women are manipulative, the family unit is the most important thing, the family you marry into is really important, and success is important, my ex was obsessed with being successful and doing what would make his mother proud. she was very image-oriented and cared excessively about how others perceived her, the family and how much money they had).
My best friend is a CP 6w5 and her parents are 2w3 and 8w7, her younger sister is a 9w1.
From what I have seen, children of unhealthy 2w3 feel responsible for their mother's emotional needs, they have to take care of her and they cannot be away from her for long.
I believe my maternal grandmother was a 2w3 who had 8 children, when my grandfather only wanted 4, he then left her because she would lie about taking the contraceptive pill. The children were then completely neglected and raised in poverty, went into care homes etc. My mother is a 6w5 and one auntie is a 9w1. It also seems to be a theme that 2w3 women date men who they deem as being below them, in an attempt to manipulate successfully "look at all I have done for you, I rescued you, you wouldn't survive without me" when in reality she wasn't doing so great before him.
