AITA for not waking my husband up for his 5AM walk?

As renowned psychologist Dr. John Gottman explains, “The single most important thing we can do to change other people is to change the way we are in relationship to them.” This situation highlights a significant breakdown in shared responsibility and communication boundaries within the marriage. The husband's behavior—yelling, assigning blame for his own forgotten alarm, and immediately resorting to silent treatment—indicates poor emotional regulation and an attempt to control his environment and his partner. While his desire to improve his health via walks is positive, framing this activity as a mandatory task and holding his wife accountable for his personal lapse (forgetting his alarm) is an unfair imposition of emotional labor. The OP's casual dismissal of the importance of the walk, though intended to minimize conflict, further escalated his already fragile emotional state, leading him to feel unsupported or even sabotaged. The OP's actions were reasonable in the context of a shared household; she is not his personal attendant. However, for future situations, a more constructive approach would be to calmly address the boundary violation regarding blame *after* the immediate anger subsides, perhaps stating, "I understand you value these walks, but I am not responsible for setting your alarm. When you yell at me, it makes me feel attacked, and I need us to discuss solutions calmly, not through blame."
