It's true that people have different expectations when it comes to communication in relationships. However, it's important to remember that it's not fair to generalize or make assumptions about people's communication preferences or behavior based on gender. In this passage, the author is suggesting that women are likely to jump to conclusions about a man's commitment or loyalty based on how long it takes him to respond to a text message, and this doesn't necessarily reflect reality. In addition, the author's characterization of women as overly emotional or irrational is outdated and demeaning.
It is wrong in implying that women's feelings and reactions are irrational, and that a man's delayed response warrants such a strong reaction. There are many factors that can contribute to a person's response time, and it is unfair to make assumptions about someone's loyalty or commitment based on a single text message.
