I have a 10 year old boy that has Aspergers. He has several freinds. However, one of his previous freinds that is in his class now has decided to ignore him. It has caused a lot of tears and even though he has other freinds he is obseesed with this one inparticular that has had enough of him. We just began seeing a Psychologist who suggested role playing which has helped a little. How do I get it through to my son some people just are not your freinds forever?
