Is ingratitude toward a spouse a greater sin than some of the major sins?

Question:
This questioner says: The author’s statement that “ingratitude after faith” indicates that ingratitude toward a spouse is a serious matter, greater than committing a major sin, meaning that the one who commits it has a greater sin than the one who committed a specific major sin. Is this correct?

Answer:
The major sins vary, my brothers. The major sins are not all the same; some are more severe than others. Among the greatest of the major sins are the seven destructive sins. The major sins vary, some being more severe than others. Ingratitude toward a spouse is among the severe major sins. Yes.
