BBJ,

If I could be brutally honest for a second, I think you are feeding the cake eater. I understand your concern with the driving conditions but you need to let go of the "call me when you get there". You may also want to consider slowing down on the family meals etc.... I think he is getting mixed signals....I know I am. Detach...think about you and the kids and nothing else. Who cares if he is sleeping or not, are you, that is the real question. So he also lies about his sleep, are you surprised....there seems to be a theme here.
I know all this detaching is tough (don't know the legal and financial ramifications) but it needs to be done.
