I should almost tell the kids that dad will be away for a while. I just don't want to cause the kids further pain. Kids with aspergers do not deal with change well. The last major change he smashed holes in the walls and did not sleep for days.
My D9 would be able to accept the fact that I an gone for a while, but with S13 it is always twice as hard and always a fight. Not making any excuses just laying out the past.
