How to tell if a woman has truly fallen in love? There's a very accurate saying: "Slow to warm up" essentially means a lack of emotional openness. Freud once said: Love is not instinct but a skill; it is a high-level ability that combines physiological attraction and social cognition, ultimately allowing one to greatly elevate their emotional system. Adults should at least learn to "not make changes, only filter," avoiding the inability to love as a responsibility to their own lives. A truly slow-to-warm-up person, when they meet someone they like, will first break their slow-to-warm-up pattern and won't use it as an excuse for others to go out of their way to please them. Love is not an excuse for others to give; it is a genuine liking from the heart. In social survival, a lasting relationship is built on an emotional woman and a rational man. The emotional woman provides emotional value, while the rational man provides economic value, creating a balance. In fact, men are not obligated to give economic value, nor is there any rule that men must provide economic value instead of emotional value. As long as both parties' contributions are balanced, it doesn't matter who gives what. Moreover, emotional value and economic value cannot be measured together. My view is that both should contribute a certain amount of what I call emotional value—I prefer to call it giving love or affection—and both should also share some economic contributions. Only then can the relationship be most stable.
