He can only live this lifestyle when he has no responsibilities such as having kids full time and getting them to bed early, getting them up early, clothing and feeding them before they go to school, etc.
If he had to do those things, I don't think he could handle going to concerts, etc.
It is too bad he has to be this way. I feel for you and the kids.
