Interesting. I think an attachment to a primary caregiver is very important but surely it cannot define a person. E.g if a child has a secure attachment with a parent but then gets bullied incessantly at school - would that not change their self esteem and therefore their attachment type?
Based on the article and my gut feelings (so I may be wrong!) I would say I was fearful-avoident and dismissive. I think I fluctuate between the two. Sometimes I think i'm bad and sometimes I think others are bad. It depends.
But I don't think how I interact with others has anything to do with my early relationship with my parents. I think perhaps it is less about other people and more about how they/their actions are perceived. E.g. I think I'm quite sensitive (and certainly was a sensitive child) and this has created a hyperaware frightened state. I think it is like purple_fins says everyone makes unintentional mistakes but a child doesn't have the understanding to realise that, it only knows the consequence so it perceives something entirely different from the original intentions.
I don't know what I'm trying to say or add to the conversation so i'm gonna shut up now!
