I will tell you about one of the main reasons why this happens. Moreover, you can influence this reason. One person, not understanding what he wants, could not convey this to the second person. And I was offended by him, because the second one just didn't understand it.

For example, you, as a woman, feel that a man does not love you. That you seem to be only formally together, but there is no emotional connection. And you may even have directly told him about it. But at the same time you didn't say the most important thing. Why do you feel this and how to fix it.

In other words, how should a man behave so that you feel loved? It's great if you have an understanding of the reasons and what needs to be done to fix the situation. In this case, it remains only to formulate it and convey it to the man.

For example, you need moral support in a difficult moment, and he does not understand that this is important to you, and does not do it. Tell him about it. Or perhaps you lack kind words from him. There is not enough to praise you for dinner, for example. Perhaps you simply do not have enough attention from him.

Find these moments in your relationship and convey to your partner how you would like him to act in certain situations
