I keep coming across things recently which are pointing big red signs at my ex. I know it's not a good idea to "internet diagnose" people, and it's unlikely it will do any good as I wouldn't be able to speak to him about it anyway, but I'm curious and wondering if it would help explain some things.
For the reasons why I think he might be affected by this condition - he seems to have no sense of thinking through the possible consequences of his actions. He's almost 30 but acts like a young teenager. Everything he does is about how it benefits him, now, this second. He seems to jump straight into relationships without ever having space for himself just to think. He get angry easily and reacts aggressively, although 99% of the time, it is all talk. When we were together he fit many of the abusive patterns and traits, but then seemed to either tail off/not follow through, or seem to have genuine (if misguided) strands of reasoning for the way he was being. He has ongoing drink and on and off drug problems. He also has the characteristic facial structure, and I know that his mum drank a substantial amount of alcohol on one occasion when she was unknowingly 12 weeks pregnant. He was born in the early 80s - is it likely this would have been picked up?
As I said, I'm not really sure what I am asking for because there's nothing I can realistically do with the information, but I was curious to know if anybody knew anything about it.
