I don't really know where to start.
I've always thought he was just very selfish, socially awkward and had anger management problems. He has never had many friends although he doesn't seem to fit the stereotypical 'aspergers geek' type in that he is good looking and dresses well (sorry if that was unacceptable terminology, not sure how else to describe it).
He and my Mum divorced, she put up with a lot from him, he used to smoke weed all the time and would sulk for days. He had one friend who actually did have mild aspergers but would rarely socialise apart from that. He has had a string of failed relationships since.
He has major anger problems, is pretty obsessed with computers, is very anxious and has problems reading how others feel, if you want him to know you need to tell him directly.
Am I reading too much into this or could he have mild aspergers?
