Swami Mukundananda
Why do my spouse and I fight so much in the evenings after work?
Spent willpower strains marriage
Willpower is used up through the day in controlling yourself, and by evening people find it has reduced. When husband and wife both have little left, the relationship goes on the rocks.
If the husband and wife both have a challenging career, their willpower gets used up during the day. In the evening, when they return, they have little willpower left.
