Your latest posts regarding your son resonated with me. My eldest is on the autistic spectrum (he was diagnosed with Asperger's but it is all under the same umbrella term now isn't it?). I'm worried about him because it will be harder for him to understand what's happening, his word is very much black and white at the moment, with no room for greys etc. I think you and your son are dealing with things "like a Pro" as NDY put it. I also think you dealt with your wife's messages appropriately, I think she wants the best for your son, and really there is no need for a text war. I'm going to try to deal with my husband's parenting advice (usually comes in the form of lectures) in a similar manner, let's hope that it works.
