These three elements are intimacy, passion and commitment/decision. Intimacy includes at least ten elements. Passion refers to the "state of strong combination with others", which can not be separated from psychological arousal and physical arousal. And commitment/decision (the difference between long-term and short-term) is considered to be the key to the difficulty of * * * (note that it is not the so-called understanding). Whether in time or in logic, it is common to decide first and then promise. Reference: The Twenty-ninth Selection of Chapter 9 of the Classic Psychology Reader (john terry F, Jr.)

If anyone is interested in a deeper level, you can come to me. I have reading notes on this. Baidu is so disappointing. When you have a problem, search this and you will find these things. Ask someone to pass by and kill me: In Intimacy, Robert J. Sterberg mentioned that once intimacy was gained, it inexplicably began to be lost. He explained that he would bring danger and lead to "the danger brought by self-opening". What do you mean by the danger of self-opening here? What are the detailed answers, references and theories? )
