They must be young if he has to stay with them on weekends. I think every weekend is unusual. But, I am not her. I think if he was sharing she would know in this case. They had a fight about it and she said she cried.

He could say he's putting money away for them to go to college. Possibly.

I think he will have children with his new wife and totally forget the ones he already has. He seems like that kind of guy.
