Do you think that your husband's salary is enough to support necessities of your in-laws and your family? If not you need to help out. If you are going to support their luxuries then you need to save most of your money. If you are planning to divorce your h based on this then you may need to start working anyway. Better to have an open discussion about the need and what's better for your kids objectively without dragging in-laws into this. Think of their monetary requirement as monetary obligation number 'n'. Also does he help around the house, kids, do chores etc at least when you are working. If he is supportive of you working in all aspects then you need to consider this positively.
