Why are husband and wife still the original match?

Otherwise, how can this sentence be circulated to this day? Especially friends with children should pay more attention. If you remarry with your children, there will be a lot of trouble, especially for older children. It is wrong to spoil them. If you take care of them, the children will think, "Why do you care about me?" Since then, there have been contradictions. After all, there is no blood relationship, so it is difficult. If the children are each other's, you must visit them often and occasionally, because you will definitely have a relationship with your ex-wife or ex-husband. Especially if the ex-wife or ex-husband has not found the other half, the other party will eat cold rice and always think that "the old love will rekindle." Therefore, the quarrel will never stop. Some ex-wives or ex-husbands are more extreme and may even cause more harm, which is often reported in the news. I care more about this. Although I haven't remarried, I have got a deep understanding, so my plan is to have more children. On the one hand, it is also for the children. If his bad habits are corrected, he will remarry, but his property must be fair and his debts must be paid off. I'm a little scared. Seriously, if you are a friend with children, please look back and see if your ex-husband or ex-wife is sincere, otherwise, when the children are independent, you will have to sacrifice yourself and find another partner for life.
