The performance is as follows: 1. Personality incompatibility: Husband and wife can't get along because they don't get enough trust. When husband and wife don't understand each other, all kinds of problems will arise. This kind of problem friction will make their marriage unhappy. 2. Differences in consumption concepts: If the husband and wife have different consumption concepts, quarrel, are unwilling to pay for each other, can't understand each other, and don't agree with each other, it means that the values of the two people are different. 3. Contradictions in life: If the husband and wife have different lifestyles and it is difficult to stand on the same line, then quarreling is indispensable. There is always no tacit understanding in chatting: the tacit understanding between husband and wife can not be achieved in a day or two. The tacit understanding between husband and wife takes time to hone, but some couples will be self-righteous. Such an idea will not bring a happy ending to the marriage, but will only break the relationship.
