As for Becky, her role as Nate’s confidant probably shifts when he makes his startling revelation. She didn’t initiate this health conversation and, like many long-term partners, she may at first listen with half an ear out of a sense of obligation. But once he drops his bombshell, she’ll be all ears and deliberately probe for more details. Given Becky’s probable fear, hurt, and anger that Nate never told her of his possible exposure to HIV, we might expect her to follow her own privacy rules rather than being constrained by his. If she later discovers that Nate has infected her with HIV, his rules will be history.
