Caring for a sick family member
Whether it’s a child, a parent, or a sibling, a family member may become very ill and require everyone’s help. If you’re married, and turn most of your attention to caring for a family member, your partner can feel that that person is getting the attention that is meant for him. It’s not selfish on his part—it’s just that he is feeling a disruption of the natural order. And, he probably doesn’t have anyone else he can turn to to care for him as much as a spouse would.
