Answer:
Mood congruent memory
Explanation:
Mood congruent memories are those memories that are related to our mood. These memories are associated with the mood at the moment of memory occur. When a person sad at a moment, memories will occur in a sad mood. When a person is happy and the memories are related to the happy moment, we create a happy mood-congruent memory.
Thus here in the above context, whenever Oliver felt sexually jealous he was felt with sad and painful memories and he recollects all those bad memories related to his girlfriend when flirting with another man.
