I've been studying love. Let me talk about my opinion. However, I don't have that great ability. I can talk about mathematics, chemistry and many other aspects. If I have that answer, I also want to know, if you want to love others, you must learn to love yourself first, because you can't even love yourself, then why do you love others? The ultimate goal of love is to make those who love and those who are loved happy. Only two people can be happy, and that can be called love. Vigorous love is very attractive, but not everyone can get it. Once it is not grasped well, it may turn into hate. If the other person doesn't love you, you don't need to insist, because loving someone can't get that person and make you collapse or even degenerate. That is not the original intention of love. Can only say that you love the wrong person, just let it go, don't entangle, let each other have each other's happiness. The reason why men are strong is to protect themselves and their families. Let me give you an example. Men are always attracted to women's breasts. Personally, women with big breasts are more attractive to men and can satisfy their original desires. But in a racial sense, women with big breasts have a greater and better chance to alleviate the initial food demand of human babies, which is one of the main factors for the higher survival rate and better living environment of human babies. There are many similar examples. You are interested in studying them yourself.
