1, Keep Similarity From the perspective of evolutionary psychology, people prefer partners who are similar to themselves. Other studies have also confirmed that the higher the similarity between partners, the more positive the relationship, especially in the fields of values, attitudes towards life, hobbies and so on. But even if the two sides are not so similar now, don't worry, because the study found that the longer the marriage lasts, the easier it is for the temper and actions between husband and wife to influence each other. This reminds us not to kill each other with a stick, even if we find that they will bump into each other after marriage. With an inclusive heart, husband and wife can become more and more alike and their marriage can last longer. 2. Fairness Some people say that there is no absolute fairness in marriage. A survey shows that marriage brings more benefits and happiness to men than to women. However, a marriage without fairness will not last long. For example, if both husband and wife have to go to work, it will easily lead to marital conflicts if the housework is unfairly distributed. For another example, even couples may quarrel over money. If one side is frugal and the other side is extravagant, there will soon be conflicts between them. If one party feels unfair, it must speak out calmly and put forward constructive solutions. 3. There should be love between lovers. Only a marriage based on love can succeed. For men and women, loving behaviors, such as laughing together and sharing daily feelings, are the key elements of a happy marriage. Love needs management, and the key is communication. No matter how busy they are, couples should keep in touch with each other every day. Even if one party doesn't want to talk, it is necessary to maintain the necessary physical communication by hugging and kissing. 4. Personality has a great influence on marriage. Psychologists conducted a personality survey on more than 1000 couples in Germany, Australia and Britain, and found that people with stable emotions, high affinity and a sense of responsibility are more likely to have a happy marriage and have stronger "compatibility" with their spouses. If both husband and wife are such people, it is certainly easier to have a happy marriage. Anxiety, negativity and other personalities will bring troubles to marriage. To overcome personality defects, couples should not only consciously correct their words and deeds, but also put communication in one place. How to run a family is happiness? 2. How to run a marriage and family? 1. Always be gentle with your husband. No man can escape from a woman's docile arms, but be careful not to be docile. When he is well, you must take the opportunity to tell him your recent thoughts, or what demands or requests you have recently, and you must say them at this moment. At this time, men will never understand rejection. Tell him you want ice cream or buy a bag. At the same time, you should remember to pour him a cup of hot tea in his study or send him a bowl of noodles and a poached egg when he works overtime, which is more effective than any housework you do. Second, learn some good dishes for him to eat. What I want to talk about here is not ordinary food. Be sure to suit the remedy to the case and cook some home-cooked dishes that my husband likes. In this way, as soon as he comes in, he will say that my wife cooked this delicious food. Usually, when he is outside, he will want to come back to you as soon as possible. Even the way you learn from recipes will make him remember you. Even as a housewife, you should have an eternal love for beauty. Ugliness and beauty are not the most important things, but you should accompany him as a beautiful woman. Remember to dress up in front of the mirror no matter how old you are. My pajamas and underwear should be more elegant, because the coat is for others to see, and pajamas and underwear are specially for my husband! Being your husband's personal assistant doesn't mean that you have to cover all the clothes at home. You can just ask the nanny or someone else to wash other clothes, but no matter how dirty and smelly your husband's underwear and smelly socks are, you must wash them. Make sure he changes clean socks every day, never let him wear out his socks, and clean every pair of his leather shoes. Make sure that the underwear he wants to wear has a unique fragrance that you have treated. As a wife, he should be able to satisfy men's desire to conquer. Sometimes, there is a lot of knowledge about men and women, and men want their wives to be gentle in the bed outside. Understand his nature of pursuing novelty and let him find the feeling of conquest in you all his life, so that he will think you are an attractive woman.
