Hey, NC, was busy this week but checking in on you. You know, my kids are autism spectrum also. About a year ago we went to D8's psych and told her about the divorce. She said the most important thing for autism spectrum children is to try to keep stability and routine and not change too much too fast.
I think what's going on in your sons' world is obviously not stable and routine, so acting out is maybe a result of that? But anyway, just wanted to say that I don't think you should blame yourself in anyway. You're the stable rock for them, and I think as they get older they will realize that more and more. Karen
