People with autism, particularly asperger's (which isnt used as much anymore) tend to mimic stocking symptoms and this is why they need help from a psychologist or family member to help them refocus the fixation of knowing "why". There fixation on why can make it seem like they are stocking.

Personally, I believe that someone who has asperger's tend to get confused on social skills and that's why it is hard for them to stop fixating on why and what they did in the relationship or relationship they thought they had.

If it goes beyond why and what happened, then u are at risk and need help from the cops because that is not autism or asperger's, that is becoming unsafe.
