Wow, that is hard stuff. Life is full of experiences and I am grateful that I have been allowed a lot of experiences, most of them positive.
While I did not have an abusive relationship, my first real one was very unhealthy, and it is true - love makes blind.
I am a software developer, and I think very much in rules. I have problems when the situations do not match my expectations. A friend has suggested that I might be ever so slightly on the autistic spectrum. So, analyzing past decisions (apart from teenage times, I just shudder), gives me usually the same answer: with the information and experience available at the given time, I would most likely make the same decision again.
Of course, I have done things whose memories are haunting, I am sure everyone has that. I found talking about those every helpful, so, I can understand that writing it down and sharing it i.e. owning is liberating.
I can only agree with @Mikiesboy that the constant questioning of the past is not helpful. It cannot be changed. We can only decide on what is ahead of us.
But now to answer the actual question: no. I have read stories that gave me an insight into how other people might "tick", but that is it.
All the best!
