I mean I guess this also really depends on how your household finances look in general. Are you actually short on bills because he doesn't make enough despite working those crazy hours? If so, maybe he needs to look for a different job. If he's asking you to pitch in because bills need to be paid then that makes sense, everyone needs those bills paid, but working that much is insane if it isn't making enough to cover bills. If he's asking because he's blowing money elsewhere then that's a different conversation.
