Answer:
The answer is: fatal attraction.
Explanation:
Although the concept of fatal attraction might seem more dramatic in popular culture, in psychology and scientific studies on relationship dinamics, it is used to explain a rather common relationship pattern. It refers to the end of the relationship on the cause of a characteristic that used to be percieved as attractive and is now percieved as negative.
In this case, Chris was viewed by Gene as spontaneous, and he used to be attracted to her because of that characteristic, but now, the same characteristic is percieved by Gene as negative, to the point of ending to relationship because of it.
