Explain from the perspective of Buddhism that this life is husband and wife, so what is the relationship in the last life?

There is a popular saying in Buddhism: husband and wife are predestined friends, and there are good karma and bad karma. This is the most reasonable. Because of ignorance, all sentient beings are transformed into six Tao from generation to generation, whether it is man, ghost, hell, heaven or Asura, it is karma. The reason is its own internal conditions, such as seeds and fate, and external conditions related to internal factors, such as soil, water, temperature and other factors affecting seed growth. The reason is the relationship between internal and external factors, and all the reasons are sufficient, just like a seed will grow naturally in an environment with suitable growth conditions. So, what caused the six divisions of the wheel of karma? It is our physical karma (good and evil things done by the body), oral karma (caring for or hurting people) and intentional karma (good and evil thoughts) that will become seeds when conditions are met and circulate in six different ways.

Back to the relationship between husband and wife, husband and wife are fate. This fate was created in a previous life. This last life is not as simple as last life, but the fate forged in countless cycles, with good fate and bad fate. There is a song: We are in the same boat through thick and thin for a hundred years, and the pillow sleep is honed for a thousand years, that is, the love between husband and wife, which shows the deep love between husband and wife. This relationship between husband and wife may not be husband and wife, or brothers and sisters, or father and son, mother and daughter, or friends and colleagues, or enemies, or people and pets, or similar natural enemies of animals, but it must have a characteristic, that is, it is obsessed with each other, or it is kind, or it is hateful, or it is loving. When you are of the same generation of the opposite sex, all karma is sufficient, that is, you may become husband and wife, "pay their debts", and repay the kindness, that is, your husband and wife love each other and have grievances, that is, you are either married or angry. Most of life is a feud, and most couples are entangled in this life.
