Men's water and women's fire-a couple who are incompatible with water and fire. They eat at home and sleep outside, because two lives kill each other. What do you mean by half-life and half-life

It means that a man's life is life, and a woman's life is life.

Although married, there are also affairs of cheating, (sleeping outside refers to this aspect)

The destinies of two people are complementary and incompatible.

Half-life marriage and half-life sorrow mean that this kind of pain and trouble will last as long as this marriage lasts.
