Yes, a lot of people internalize things as their fault. I had that issue with relationships. I thought if my ex cheated on me, it was because I had failed or not tried hard enough... I was wrong.
Similar with abusive relationships. If you had been a better child dad/mom wouldn't have beaten you... moving on is realizing that you had zero control over that situation and the fault was entirely your dad/mom. But a lot people can't dissociate emotionally to begin to see things that way, esp if they are still hung up parental approval.
I'm in my 40s and it's terrifying to me how many people I meet who are still hung up on parental approval or angry at their parents for not doing more for them... it's pathetic.
