Hi welcome dogfish, the teenage years are hard anyway.... my son who is on the autism spectrum now 14 hates change, but I have found allowing him his quirks and differences really helps, if he needs space, we agree a later time... school days often he needs a good half an hour or more in his own space before anyone talks to him. Its often the little things that really help and if he closes down do find the odd text, email a better way to communicate sometimes. Pressuring him will just make him angry and frustrated, and even trigger a melt down. But I also believe clear boundaries and rules are vital to keep an even balance, we are close and talk about everything, but I am on the autism spectrum myself so do get his need for space.
