The logic of dream interpretation is that the collapse of kang symbolizes a place to settle down and live. The kang collapsed. There must be a fire. Fire symbolizes people's efforts and hardships, so that they can get a peaceful sleep at night. Now, instead of fire, it is water. The cold water shows that the warmth on the kang board has been lost and the habitat has lost its temperature. And then lost the warm power to maintain the family. Therefore, it is interpreted as: my wife has an outside heart and no longer works with you. This should be an accurate answer.
Maybe this is just your subjective unnecessary worry, not an objective fact. Everything depends on human efforts, and the development of things also depends on human efforts.
