PS - girl, you have the patience of a saint. I would have castrated my h by now, and with a blunt knife [sorry any guys reading this]
There is no criticism implied here, btw, just heartfelt admiration. It is good that he is going to counselling, and with a counsellor who sounds like she will not let him play games. I think kids are pretty resilient if at least one of the parents is strong.
Interestingly, my middle son who at the time of the bomb appeared to be taking it the most calmly, is now suffering from depression and anxiety. He told me a couple of days ago that he really admires how I have got myself together! As I think I posted, according to my h, my kids reaction to the bomb and to him is all my fault!! But he is a lot loopier than yours. Not quite up there with Always' h, but making a bid for the top 10 loonies on these boards. Mind you there is stiff competition.
Vent whenever you need - you have my total support and admiration for what you are doing.
