My money is my money, his money is my money feminist here.
and if he dies and his money goes to his mom and not his child? Also, OP has put him as the beneficiary of her policy and money. If he doesn't want to leave it to his spouse, he should make provisions for the child. Otherwise he is not paying his share of his child's future expenses, just like he would be forced too if they divorced.
and also, at issue here is not 'his money'--for he will be dead! It will either be for her and the kid or someone else. And she is asking whether she should be offended (worried ,etc) that her husband refuses to provide for her and or their child in the event of his death, and the answer is yes. This is not about his money/her money--it is about who he values.
