It sounds as if he showed very low initiative. He placed all of the decision making on her shoulders, decided to not burden himself with such things. Meanwhile, he was free to do as he pleased for some time.
He did not realize this error until she started giving signs that he can’t just sit around so he contributed but it was half-hearted, with the sole goal:
“don’t make her angry”
which is an immature goal.
A “don’t make woman angry” is the goal of a manchild.
