I think he probably does have ASD and a personality disorder, he appears quite emotionally unstable. Everyone is on a spectrum and not all patients present with the same difficulties. He clearly has very unstable interpersonal relationships, emotional dysregulation and low tolerance for stress/distress. Probably why he struggles to commit to things. It’s sad, but he’s clearly not used to taking responsibility for himself and his actions. He probably is vulnerable at times. I reckon he is very well known to local mh services and they are used to responding to his crises and assessing his risk. I’m sure he’s not easy to deal with at all!
