I don't particularly talk to my mum.
In the past, I've told her that, if she ever wants me to look after her, can I dish out the same treatment she gave my other siblings? She 'cried' and set the 'good' siblings against me, and told me that I was evil. Nah, not evil, just honest.
The problem people have is having to admit that their parents are abusive and that they were, in fact, good kids. And the problem was that the adults could not manage their emotions and had no boundaries.
It's easier for our child-self to take the blame, as it lets them off the hook.
It took me a long, long time to admit the depravity of my parents' ways. But I was always in turmoil and unsure why. I always felt slightly uneasy around them and the 'good' siblings.
I always thought I was this unlovable person.
I struggled because the truth did not align with my (subconscious) wish; that my parents really did love us.
Did they f*ck!
Thy did it for the money! (we were fostered).
