Just a guess, but maybe at his age, he is surrounded by females all the time and with the father working all the time, that may be the structure that he needs.
It is possible that if he had more of a male figure around him, his attitude would change. I do believe that the father has to work like he does, but more of his attention to the son can make a lot of difference.
I think it is very true that it is harder for a women to raise a boy to be a man and you definately need help. If your husband can understand what is going on as opposed to you just telling him what happened, he will step up to the plate, if he can. If not, your problem has potential to get worse.
I know people think that when their child doesn't act they way they feel they should, the first thing they do is take them to be evaulated. This tends to put a lable on kids that shouldn't be there when the answer is right at home.
Just take it under consideration and talk to your husband instead of using insurance on a problem the two or you can solve.
